摘要

介绍了一种用于桥式传感器的低成本通用传感器信号条件专用集成电路。该ASIC采用标准双金属、双聚0.8 /spl mu/m硅CMOS工艺生产，可校正传感器的偏置、偏置温度系数、灵敏度和灵敏度温度系数。我们已经使用该ASIC来信号条件硅压阻压力传感器在-40/spl°C至125/spl°C的温度范围内，总误差小于传感器满量程输出(FSO)的/spl + /1%。该ASIC可为压力传感器、霍尔效应传感器和MR/GMR传感器等桥式传感器的校准提供低成本的解决方案。

A universal sensor signal conditioning ASIC

This paper described a low cost universal sensor signal condition ASIC for bridge type sensors. The ASIC was produced with standard double metal, double poly 0.8 /spl mu/m silicon CMOS process and can correct the sensor's offset, offset temperature coefficient, sensitivity and sensitivity temperature coefficient. We have used this ASIC to signal condition silicon piezo-resistive pressure sensor to a total error of less than /spl plusmn/1% of the sensor's full scale output (FSO) in a temperature range of -40/spl deg/C to 125/spl deg/C. The ASIC can provide a low cost solution for the calibration of bridge type sensors such as pressure sensor, Hall effect sensor and MR/GMR sensor.
