Abstract
A signal processing circuit. In some embodiments, the signal processing circuit includes a first sample and hold circuit and a second sample and hold circuit. The first sample and hold circuit may include: a hold capacitor; an input switch connected between a common input node and the hold capacitor; a signal path amplifier having an input connected to the hold capacitor; and an output switch connected between an output of the signal path amplifier and a common output node. An input of a voltage feedback amplifier may be connected to the hold capacitor, and an output of the voltage feedback amplifier may be operatively coupled to an internal node of the input switch.
