摘要：
An alternative temperature compensation technique for a silicon pressure sensor is presented. By using on-chip heater and temperature sensing electrodes, a thermostatic control loop is implemented. The sensor is biased at a reference temperature, which is maintained with high accuracy over a specified range, hereby eliminating the dependence of the pressure sensor output on ambient temperature. No additional calibration procedures for temperature compensation or external temperature sensing elements are required. Modelling aspects as well as experimental results are discussed.
