perform noise in transient analysis using H-Spice...how 2 do tat ? can we realise te noise using transient simulation...take a cmmn source single stage as a example !!! i got te Von=4nV/ √ Hz in ac analysis
input reffered noise = output noise/ gain of te bandwidth ?
is tat inp refered noise n equivalent input noise is same ?
sum attachments will b rely helpful....10q

It is possible for simulators which can store a transient point and use this op storage as an operating point for an AC analysis including noise.
I think Spectre and Smash can do this. But I think it is not possible via the ADE for Spectre.

| do u hav ny articles tat shows te correct way of simulating noise in spectre ??how 2 perform noise figure waveforms?? i tried n cant get a solution..te rest such equivalent inp/out & squared inp/out noise voltg can b simulated n manage 2 get te waveform..except noise figure ?? Thn how abt using H-Spice??do u hav ny idea....
