Double-sampled integrator system and method thereof

摘要

A double-sampled feedback integrator system includes a sampling module having multiple switched capacitors. The switched capacitors of the integrator system are opened and closed based upon a polarity of the signal input to the double-sampled feedback integrator system. The integrator system can be used in a sigma-delta converter. A sigma-delta converter includes a double-sampled common-mode correction circuit having multiple switched capacitors to provide common-mode rejection to a system.
