Original Abstract Submitted
A sensing circuit includes at least a first gain stage and a controller for controlling the operation of the first gain stage. The first gain stage includes an amplifier having at least one input and one output, and a feedback loop coupled between the input and the output of the amplifier. The feedback loop includes a first capacitor coupled between the input and the output of the amplifier, and a second capacitor having a first terminal coupled to the input of the amplifier through a first switch and a second terminal coupled to the output of the amplifier through a second switch. The second capacitor is configured to be coupled in parallel to the first capacitor during a first portion of a measurement cycle, and disconnected from the first capacitor during a second portion of the measurement cycle.
