interdigitation matching for current mirror devices and common centroid for differential pair devices:
Interdigitation Matching:
Purpose: Interdigitation is employed primarily to mitigate gradient errors in device matching.
Explanation:
In interdigitation, adjacent devices are interleaved...
Thanks, LvW for your replies. Here I attached a figure where the Gain Margin calculated at -180-degree phase plot. I don't understand why cadence calculate it 0 degree.
I am a newbie in Analog IC design. Please help to create a test bench for measure the PSSR of my Two Stage OTA in cadence. Some resources, someone applied AC analysis to measure te PSSSR on the other hand someone used XF noise analysis. Please can anyone help to me for the standard methods.
Hi, i am a newbie in Analog IC design. I perform a stability analysis of my Two Stage OTA. As from the textbook the Gain Margin calculated to the -180 phase along with the (0 - Calculated Gain). But in Cadence from the Direct Plot Grom, I get the GM= 7.67dB, when i cross check with the Gain and...
