ABSTRACT:
A linearizer circuit which corrects inherent nonlinearity of a capacitive pressure sensor is provided. The linearizer is based on an operational amplifier configuration including a feedback network of switched capacitor type that is switched between a first switching phase and a second switching phase .In this switched capacitor configuration, DC gain of the operational amplifier configuration in the second switching phase can be adapted to realize a linearization function required to substantially linearize a non-linear capacitance-pressure characteristic of a capacitive pressure sensor when the capacitive pressure sensor is connected to be part of the feedback network.
