using Cadence, spectre simulator. (do not have synopsys, Yes i know HSPICE is golden standard)
Is the discrepancy because of the PDK accuracy? I am not sure. Because I found weird BW result in other circuit. That's why i constructed a simply testcase, common source amplifier
Av_DC_dB --> value(dB20((VF("/out") / VF("/vgs"))) 1 ?histoDisplay nil ?noOfHistoBins 1)
Av_DC --> mag(value((VF("/out") / VF("/vgs")) 1 ?histoDisplay nil ?noOfHistoBins 1))
3dB_BW --> bandwidth((VF("/out") / VF("/vgs")) 3 "low")
where vgs is input with small signal acm=1mV, out is output node
the gm & Cxx are obtained from OP (in dc)
