cmfb question
the difference betwn open loop and closed loop is loading capacitance / feedback capacitance.
As you know, it changes the pole locations from your calculation
Unless you consider the loading capacitance with each phase , you may face those situation
I am now concerning delta sigma loop for adc.
In tran simulation, i can evaluate the effect of distortion to total performance as you told.
However there isn't amp thermal / flicker noise contribution in transient sim.
Those noise is consist of distortion from switched cap circuit by RC time...
Hi all;
I need a method to measure the thermal/ flicker noise contribution in frequency domain
So i run the transient simulation and noise simulation in Spectre, both way
Once i got the data-stream from the transient simulation and convert frequency domain with FFT//
there didn't exist...
