Hi, All:
For low-voltage (1-Volt), low power (nW), high speed ( IF > 10MHz),
switched-capacitor sigma-delta modulator design,
1. Use Switched opamp for solve low voltage.
2. Double sampled feed into integrator for high speed.
3. Pseudo n path on single opamp for low power.
Question:
1. Switched Opamp (SO) increases power consumption in every critical
switch, double sampled, double power.
2. Does it is possible to accomplish bandpass sigma delta modulator
using only ONE opamp (Integrator) working in Pseudo n path
architecture.
Please give any suggestion or comment, thanks a lot!
