General Description
The 4083C makes use of an Elantec fully complimentary oxide isolated bipolar process to produce a patent pending current in current out four quadrant multiplier Input and output signal summing and direct interface to other current mode devices can be accomplished by simple connection to reduce component count and preserve bandwidth The selection of an appropriate series resistor value allows an input to accept a voltage signal of any size and optimize dynamic range The differential outputs offer significant performance improvements which greatly extend the usable gain control range at high frequencies The bias current is programmable to accommodate the voltage and power dissipation constraints of the package and available systems supplies The devices can implement all the classic four quadrant multiplier applications and are uniquely well suited to gain control and signal summing of broadband signals

General Operating Information
IZ Input (Bias Divisor) and Power Supplies
The IZ pin is a low impedance ( k 20X) virtual ground current input It can accept positive current from a resistor connected to a positive voltage source or the positive supply The instantaneous bias for the multiplier gain core is proportional to this current value Negative applied current will put the multiplier portion of the circuit in a zero bias state and the voltage at the pin will be clamped at a diode drop below ground The part will respond in a similar manner to currents from a current source such as the output of a transconductance amplifier or one of its own outputs The overall transfer equation for the EL4083 is K(IX c IY) IZ e (IXY - IXY) K E 1 As can be seen from the equation the Z input can serve as a divisor input However it is different from the other two inputs in that the value of its current determines the supply current of the part and the bandwidth and compliance range of the outputs and other two inputs Table 1 gives the equations describing these and other important relationships These dependencies can complicate and or limit the usefulness of this pin as a computational input The IZ dependence of the impedance of the multiplying inputs can be particularly troublesome See the IZ divider and the RMS 2 circuit sections of the application note for some ways of dealing with this The primary intended use for the Z input is as a programming pin similar in function to those on programmable op amps This enables one to trade off power consumption against bandwidth and settling time and allow the part to function within its power dissipation rating over its full operational supply range (g4 5V b g16 5V) The E4083 has been designed to function well for IZ values in the range of 200 mA k IZ k 1 6 mA which corresponds to IX and IY signal bandwidths of about 50 MHz to over 200 MHz Higher values of IZ may cause problems at temperature extremes while lower values down to zero will progressively degrade the input referred D C offsets and reduce speed Below about 50 mA of bias current the internal servo amplifier loop which maintains the IZ pin at ground will lose regulation and the voltage at the pin will start to move negative (see Figure 10) This is accompanied by a significant increase in input impeddance of the pin Figure 11 shows the A C bandwidth of the IZ input as a function of the D C value of IZ Figures 6 and 7 show the bandwidth and 1% settling time of the multiplying inputs IX and IY as functions of IZ
IX and IY (Multiplier) Inputs and Offset Trimming
The IX and IY pins are low impedance (IZ dependent) virtual ground current inputs that accept bipolar signals The input referred clip value is equal to IZ c 2 while the full scale value has been chosen to be 1 25 c IZ to maintain excellent distortion and linearity performance Operating at higher full scale values will degrade these two pa-

General Operating Information
Contd rameters and to some extent bandwidth while improving the signal to noise performance feedthrough and control range The EL4083 is fundamentally different from conventional voltage mode multipliers in that the available input range can be tailored to accommodate voltage sources of almost any size by selecting appropriate input series resistor values If desired one can interface with voltages that are much greater than the supplies from which the part is powered Current source signals can be connected directly to the multiplier inputs The parts' dynamic range can also be tailored to a large extent for a current signal by the appropriate selection of IZ These inputs act in the same manner as a virtual ground input of an operational amplifier and thus can serve as a summing node for any number of voltage and or current signals Outputs of components such as current output DACs transconductance amplifiers and current conveyors can be directly connected to the inputs Ideally a multiplier should give zero output if either one of its multiplying inputs is zero A nonzero output under these conditions is caused by a combination of input and output referred offsets An output referred offset can be thought of as a fixed value added to the output and thus only affects D C accuracy An input referred offset at a multiplying input allows signal to feedthrough from the other multiplying input to the output(s) The EL4083 is trimmed during testing at Elantec for X and Y input referred offset for IZ e 1 6 mA The internal trim networks provide a current to each input which nulls the feedthrough caused by internal device mismatches These current values are ratioed to the value of IZ so that the input referred nulls are largely maintained at different values of IZ However there will be some mistracking in the trim networks so that the input referred null point will deviate away from zero at values of IZ lower than 1 6 mA Figure 9 shows optional external input and output referred offset trim networks which can be used as needed to improve performance As mentioned the output referred offset only affects D C accuracy which may not be an issue in A C applications In gain control applications one may only need to null feedthrough with respect to the gain control input In gain control (VCA) applications the X input should be used as the control input and the signal applied to the Y input since it has slightly higher bandwidth and better linearity and distortion performance
Current Outputs (IXY IXY) Feedthrough and Distortion
Another unique feature of the EL4083 is the differential ground referenced current output structure These outputs can drive 50X terminated lines and reactive loads such as transformers baluns and LC tank and filter circuits directly Unlike low impedance follower buffers these outputs do not interact with the load to produce ringing or instability If a high level low impedance output is required the outputs can be recovered differentially and converted to a single ended output with a fast op amp such as the EL2075 (see Figure 19) The outputs can also drive current input devices such as CMF amps current conveyors and its own inputs directly by simple connection Figures 12 and 14 show the nulled gain and feedthrough characteristics of the IXY and IXY outputs which are virtually identical and differ only in phase Figure 12 is with the A C signal applied to the X input with Y used as the gain control and in Figure 14 these signals are reversed Note that in both cases the signal feedthrough rolls up and peaks near the cutoff frequency This is quite typical of the performance of all previous four quadrant multipliers Figures 13 and 15 show the corresponding gain feedthrough characteristics for the differentially recovered output signal IXY-IXY Note that in this case the peak feedthrough at high frequencies is lower by more than 40 dB

This has a maximum 3 dB bandwidth of 130 MHz and settles to 1% in 25 ns Figure 19 uses an EL2075 at the outputs as a differential to single ended converter with gain to take advantage of the performance enhancements of the differentially recovered output mentioned above and to provide a high level low impedance drive The b 3 dB bandwidth of this circuit is over 150 MHz using good layout techniques However to achieve this bandwidth one must restrict the output swing to little more than 1 Vpp to avoid running into the 500V ms minimum slew rate of the EL2075 Table 2 shows the input signal assignments for the applications listed above

Other Applications
Elantec has also published an applications note covering other applications of the EL4083 These include dividers squaring and square rooting circuits several RMS and power measurement circuits and a wideband AGC circuit Also presented are two polynomial computation examples for video and some HDTV quality fader and summing circuits The EL4083 has been found flexible enough to easily implement all of the classic four quadrant multiplier applications and also offer interesting new applications possibilities tween IZ and NS is IZ e 200 mA c NS All other inputs can accept time varying signals The model will provide good transient and frequency response and settling time estimates as well as time domain switching results Input and output impedance and overload responses are correctly modeled The D C current drawn from supplies for a given value of IZ is also correct Noise PSRR and the temperature dependence of A C parameters such as frequency response and settling time are not modeled Linearity and distortion results from the model will be worse than the real part by about a factor of three and do not show the correct frequency dependence The macromodel is constructed from simple controlled sources passive components and stripped transistor and diode models As such it should be usable perhaps with slight modification on all but student or demonstration simulators where the model's size may be a problem

This macromodel is compatible with PSPICE (copywritten by Microsim Corporation) It has been designed to work accurately for fixed values of IZ (bias) in the range of 200 mA to 1 6 mA The additional simulation burden imposed by including provision for a time varying IZ was thought not worthwhile The value of IZ is specified to the model by the parameter NS The relation be-
