  • Re: Different op amp gains using different spectre analysis

    Thanks for reply, However I am facing a very strange problem in my simulation, please help me with this: I am running a parametric simulation to experiment & get the optimal bias current of Op-Amp . For this I gave a list of "I_bias" as "5u 7u " in the parametric analysis window...

  • Different op amp gains using different spectre analysis

    Hi all, I am new to analog design. I have created an op-amp schematic and tried to get open loop gain by 2 ways: (Simulation uses cadence virtuoso) 1) Transient analysis: applied a ramp pulse of 0->VDD to +ve input [with a dc value of VDD/2] and kept -ve input to Vdd/2, then plotted Vout vs V+ and...
