Abstract
In accordance with embodiments of the present disclosure, a method of neutralizing voltage kickback associated with a reference buffer of a switched capacitor based data converter having a first switched capacitor coupled to an output node of the reference buffer wherein the first switched capacitor comprises at least one first capacitor and at least one first switch may be provided. The method may include coupling a passive network to the output node of the reference buffer in response to a presence of a condition for encountering the voltage kickback in order to create an approximately equal and opposite voltage kickforward by the passive network to at least partially neutralize the voltage kickback.
