EL2120C
100 MHz Current Feedback Amplifier
The EL2120C Macromodel
This macromodel has been developed to assist the user in simulating the EL2120C with surrounding
circuitry It was developed for the PSPICE simulator (copywritten by the Microsim corporation) and
may need to be rearranged for other simulators particularly the H operator It approximates frequency
response and small-signal transients as well although the effects of load capacitance does not show
This model is slightly more complicated than the models used for low-frequency op-amps but is much
more accurate for AC
The model does not simulate these characteristics accurately
noise
non-linearities
slew rate limitations
temperature effects
settling time
manufacturing variations
input or output resonances CMRR and PSRR
Revision A March 1992
Enhancements include PSRR CMRR and Slew Rate Limiting
