Hi,
I need an ideal differential OpAmp/OTA to simulate Active-RC integrators in cadence.
I have read the previous threads in the forum about this topic. I know that I can use a very high-gain VCVS and emulate the poles using RC.
The input to the system is a sine wave with an amplitude of 1 mV and a DC level of 0.5 v. The problem is, the DC level at the output is also multiplied by gain.
Can anybody give me a suggestion on how to fix the output common-mode in VDD/2? I probably need a CMFB, but I don’t know how or where to connect it.
