Re: what circuits can simulate these parameters of a full OP
Hi, all: when I simulate the DC character, AC character, TRAN character, CMRR, PSRR, ICMR( the OPA is a full differential OPA whose CMFB is switched capacitor circuits), I get rid of the CMFB circuit, i.e. switched capacitor circuits, and I add a DC voltage to the cmfb, I do not know what I do is right or not.
the attachment file ed_OPA_1st.pdf is the full differential OPA, and the opa.pdf is the circuit that I simulate the DC character, AC character, TRAN character, CMRR, PSRR, ICMR of this circuit.
regards!!
