cmrr pssr site:edaboard.com xf analysis
It is rapported that the unity-gqin frequency of the amplifier should be 3-4x the sampling frequency of the switched capacitors circuit.
1.What about the 3db frequency in an open loop configuration?
2.I use a SC circuit to control the CMFB.
Can you give some information about pss analysis (is xf also relevant?) and how to simulate the gain?
3.How can i simulate PSSR and CMMR with the SC CMFB circuit?
