I am designing a second order low pass delta sigma modulator. I want to calculate the real (finite gain) transfer function of the integrators which are noninverting and delaying. I have searched on the internet and found the transfer function is 1/[1-(1-1/A)z^-1]. However, I can't derive it...

How to set the ideal switch in cadence? When 3.3V, the switch allow signal to pass through it. When 0V, the switch block the signal to pass. How to set the switch?

I am now constructing an ideal model of SC second order delta sigma data converter in Cadence. The structure that I use is CFFB. However, I dont know how to make the feedback path(output from one bit quantizer to first and second SC integrator). Can anyone tell me how to do it? Thanks.

i make the changes, and the follwoing is the simulation result. I think this is the correct result, right?
Actually, i want to change the single end output to differential outputs which will be used as integrator in sigma delta ADC. So, I want to know how to simulate an fully differenetial...
I have draw a folded cascode opamp and I want to simulate it open loop gain and phase.
The way that I used to simulate an opamp is to connect a AC source to the non-inverting input and connect a 1F capacitor to inverting input. Also connect a 1G resistor between output and inverting input. (P.S...
