ideal opamp circuit in gyrator circuit in differential configuration is to be designed in cadence tool. So what parameters should be taken care of and what should be done to make this opamp as an ideal one?
i want that the cmos differentil opamp should have a higher open loop gain that is required for an ideal opamp.But at higher frequeny, open loop gain decreases. so how to work t higher frequencies such that gain is constt. and high?
The term "ideal opamp" describes something that can't be actually made or designed in actual technology.
It's e.g. required for circuit stability that the loop gain falls below unity at a finite frequency. For this reason, any amplifier to be used in a feedback configuration can't have frequency independent constant gain. The practical design challenge is to make an amplifier with high gain-bandwidth product (GBW) and sufficient phase margin so that it can be operated in a stable feedback loop.
You'll need to mention real amplifier specifications required for your design rather than imagening "ideal" OPs.
the frequency should be 20 GHz and the differential opamp should be stable and should have less error.
as frequency is inversely proportional to the open loop gain and directly proportional to error
