Abstract
In accordance with an embodiment, a system includes a programmable gain amplifier having a switchable feedback capacitor coupled in parallel with a first capacitor and a controller. The controller is configured to couple the feedback capacitor between an input node of the programmable gain amplifier and an output node of the programmable gain amplifier in a first gain setting, and switch a first terminal of the feedback capacitor from the output of the programmable gain amplifier to a reference node while a second terminal of the feedback capacitor remains coupled to the input node of the programmable gain amplifier for a first time period when transitioning from the first gain setting to a second gain setting.
