Title: bnadwidth estimation for the mixed circuit Post by john_xu on Jul 2nd, 2006, 11:19pm I am designing a CMOS circuit composed of a OPA+cascaded inverter buffers. This circuit is to ampify a weak signal and bufferd it to a CMOS signal. I wonder if I want to get the bandwidth of this signal, how can I to do the simulation?The ac simulation can do it? It is more like a mixed analog digital circuit, the ac analysis is meaningful for the -3dB bandwidth estimation? Or I should monitor the transisent analysis to assess the bandwidth?
