  • Publication number: 20130278334
    Abstract: Embodiments of a capacitance sensing system including an integrating amplifier and methods for operating the same to provide a higher slew rate and bandwidth are described. In one embodiment, the integrating amplifier comprises an input stage including an inverting input coupled to an electrode of a capacitor to sense a capacitance and a non-inverting input coupled to a reference potential, and an output stage including a compensating capacitor coupled to an output. The compensating capacitor comprises two smaller capacitors coupled in parallel and a switching element configured to open when the integrating amplifier is operated in a RESET mode decoupling one of the two smaller capacitors from the output to decrease capacitance of the compensating capacitor.
