Please log in for more thread options 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. | |||||||||||||

Hello, When you just want to see the effect of slew rate, you could use some Hspice building blocks. The "slew" block enables you to specify positive and negative going slew rate. The output impedance of this block is zero (in case of voltage slew rate limitation). I don't know whether this matters for your application.
