A novel switched capacitor signal conditioning circuit is developed for differential capacitive sensors. The main advantage of the proffered m ethod lies in the fact that it accepts sensors possessing either linear or inverse characteristics and provides a linear output. Moreover, the output is dependent only on a pair of DC reference voltages and the transformation constant of the sensor. Hence increased linearity and accuracy is easily achieved by employing precision DC reference voltages. Results from the tests on a prototype elucidate the practicality of the proposed method. © 2005 IEEE.
