摘要

In this paper, the design of a signal conditioning analog front-end (AFE) IC for an automotive piezoresistive type pressure sensor is presented. To improve the pressure-sensing accuracy and compensate for variations in the pressure sensor and signal conditioning IC, gauge factor calibration, digital automatic offset, and gain calibration are proposed and implemented with low power consumption.
