Title: function of loop gain from 'stb' as input to 'pz'
Post by doho on Aug 10^th, 2007, 6:43am

I am investigating whether or not the metastable state in a circuit (see attachment) has poles in the right half plane. So I want to take the loop gain (L) from 'stb' and do 'pz' on L/(1-L). Is this possible in Spectre?

I would also be bery glad to hear if you have any other suggestions on how I could verify that: the state when the currents are shared equally between the transistors, is really metastable. With metastable I mean that any noise guaranteed will bring the circuit to a stable state.
