SPICE opamp model with adjustable slew-rate

Mar 11, 2008 2 Replies

Hi.



I want to examine the effect of limited slew-rate (real) opamps that I use in diode rectifiers as part of asynchronous amplitude demodulators.



Therefor I'm searching for a (spice) opamp model with adjustable slew rate.



The ideal model "opamp" of PSpice has adjustable Gain-Bandwidth- Product available in the properties box, but no slew rate...



As simulation tools I prefer PSpice and SystemVision.


You might take a look at free LTspice available at:

It includes a part called universalopamp2 that has almost all aspects adjustable, including slew rate.
