(English Abstract) |
A digital vacuum pressure sensor is designed, fabricated, and characterized using a packaged MEMS analog Pirani gauge. The packaged MEMS analog Pirani gauge requires a current source to heat up a heater in the Pirani gauge. To investigate the feasibility of digitization for the analog Pirani gauge, its implementation is performed with a zero-temperature coefficient current source and microcontroller that are commercially available. The measurement results using the digital vacuum pressure sensor showed that its operating range is 0.05–760 Torr, which is the same as the measurement results of the packaged MEMS analog pressure sensor. The results confirm that it is feasible to integrate the analog Pirani gauge with a commercially available current source and microcontroller. The successful hybrid integration of the analog Pirani gauge and digital circuits is an encouraging result for monolithic integration with a precision current source and ADCs in the state of CMOS dies.
