construct a test bench which is closed loop and gain=1.add a vdc =0 as the input of the opamp. spectre provide noise analysis. you could choose the differential output as the output pair. and input source as the noise source. After simulation you could print noise summary to see the total (...)
On spectre you can use the noise analysis and then choose the noise source to be your input and the output is the opamp output Run the simulation go to Results-->Print-->noise Summary Rania
In cadence simulation, the opamp and comparator is almost ideal(no offset and no noise at tran simulation), then the INL and DNL at the results of simulation is better than the results of chip test. How can I add this nonideal facts at cadence, and get a statistical results, and modify my design. Thanks your (...)
