Title: How to build amp's open loop gain simulation circumstance? Post by bitplex on Oct 8th, 2016, 6:05am Hi all. A simple question from a freshling. How to build an amp's open loop gain simulation circumstance? for eg. xi0 gnd inn inp out vdd amp r1 inn out 1g c1 inn gnd 1g vinp inp 0 2.5 ac 1 It works, I don't know if there are another way to get this. Thank you. |

Post by Ken Kundert on Oct 9th, 2016, 1:24pm The approach you are taking, using a low pass filter to break the loop, is not accurate. You should use Spectre's STB analysis. There has been plenty of discussion of loop gain analysis and stb analysis on this forum. Look around for more detail. -Ken |
