Low voltage, low power, high speed, sigma delta modulator design

[boki]

Hi, All:

For low voltage, low power, high speed, sigma delta modulator design,

What problems exist in this kind of archtecture implemetation:

"Double Sampling" + "Finite Gain Compensation" + "Pseudo N-Path"

Component:
* Switched Opamp
* Switched Capacitor
* 1 bit A/D, D/A

Thanks a lot!

Boki.
