SCF double sampling technique for Pseudo-N-path

[boki]

Hi, All:

I have two switched capacitor filter design questions,

1. If design Switched-Opamp on Double sampling technique, could it
function work on pseudo-N-path or not?

2. If there are other archtectures faster(high operation frequency)
then Pseudo-N-path?

Thanks a lot!

Yes, but capitor hysteresis will create cross-over between the paths.

AD-memory-DA, not that expensive and much better.
