 12 May 2008 9:38 switched capacitor integrator |
|

Hi :
I have a switched capacitor integrator, and i try to find the op-amp finite gain.
The one way is give a "dc" input, and check out the saturation output voltage.
(From the transfer function (z=1, DC), can get the finite gain of op-amp)
But, if the integrator is a "correlated double sampling" topology, which has
effectively doubled finite gain. (A-->A*A)
Can i use the same method ("dc" input), to check out the saturation output voltage ?
(Because i cannot get the right result from simulation)
Is any other ways can help me to see this effectively doubled finite gain from spice?
thanks
