Abstract

An integrating amplifier on an IC, which comprises a feedback loop using an external device as an integrating capacitor, has added a second feedback loop that provides an additional current to the input of the amplifier, which current can be used to increase the input range of the charge that can be measured without needing another external capacitor or pad.
