    Hi, All:

    What's the different between switched capacitor and switched opamp
    technique?

    Thanks!

  2. Never head of a switched op-amp. Do you mean a chopper amp? If so, a
    chopper amp is designed to give low offset voltage, a switched capacitor
    device is usually taken to be a filter.
