The paper describes modeling of high-sensitivity MEMS pressure sensor based on a circuit containing both active and passive stress-sensitive elements: a differential amplifier utilizing two n-p-n transistors and four p-type piezoresistors. The analysis on the basis of the developed mathematical model for a pressure sensor with traditional piezoresistive Wheatstone bridge and theoretical conclusions regarding the change in the electrical parameters of a bipolar transistor under the influence of deformation was carried out.
