    Gain and Phase margin problem

    Added to that i already done the stability analysis in cadence by breaking the loop and inserting the iprobe as well. The command window is showing that the loop is unconditionally stable and it is not showing any gain and phase margin values

    Gain and Phase margin problem

    Thanks for the answer friends. Now I added CMFB to my circuit. But still i am having a problem on Phase margin. The phase degree spectrum doesnt reach -180 rather it suddenly increase. Can you people tell me why is that happening and why am not able to reach the -180 degree. Is it because of the...

    Gain and Phase margin problem

    Thanks for the reply frankrose. The opamp i am using is folded cascode for the first followed by common source as the second stage. Please find the below attached schematic. I am using the load cap as 0.1pF and Compensation cap as 500fF 1. Two stage opamp bodeplot 2. Schematic Waiting for...

    Gain and Phase margin problem

    Hello, I am designing the two stage folded cascode opamp. For the single stage of folded cascode i got sufficient phase margin of 64 degree. But when i added the second stage, the phase margin increases to 150 degree. is it correct to have higher phase margin? In order to reduce the phase margin...

    chopper stabilized opamp

    Thank you for the reply. I am designing low noise readout IC. For that I need chopper stabilization to get rid of 1/f noise. After doing some modification the input stage of the two stage folded cascode, chopper works fine. But the problem arises when the chopper is introduced between the first...

    chopper stabilized opamp

    Hello, I am working on read out circuits. I am using chopper stabilized folded cascode amplifier. The problem in the chopper stabilized circuit is when using chopper in the input stage drastically reduces the gain of the amplifier from KV to mV.can anybody help with this??
