A monolithic sensing solution for manifold absolute pressure (MAP) is presented. This work includes examination of design, fabrication, temperature compensation, packaging and electromagnetic compatibility (EMC) testing of the fully integrated monolithic sensor. The circuit uses integrated bipolar electronics and conventional IC processing. The amplification circuit consists of three op-amps, seven laser trimmable resistors, and other active and passive components. Also discussed is a summary of an automotive application MAP sensor general specification, test methods, assembly, packaging, reliability and media testing for a single chip solution.

An Integrated Barometric Absolute Pressure Sensor (IBAP) solution for barometric pressure sensing is presented here. The IBAP is a silicon bulk micromachined monolithic pressure sensor. This work includes an examination of the design, fabrication, temperature compensation, and testing aspects. In addition, options and issues related to the mounting of the IBAP device will be presented. Two techniques, including surface mounting the sensor on the engine control unit (ECU) PWB are discussed.
