CMOS电容式湿度传感器特性研究
A Study on the Performance of a CMOS Capacitive Humidity Sensor
摘要
Abstract
A study on the performance of a CMOS capacitive humidity sensor is presented. This humidity sensor was fabricated with the standard CMOS technology and the MEMS post-processing step. To test the response time of the humidity sensor,an experimental set-up was designed. As can be seen from the measurements,the sensor shows a good linearity over the testing range from 25% RH to 95% R.H. The maximum hysteresis of the sensor is 2% RH, at 75%RH. And the sensor has a short response time. No obvious drift can be found after the sensor was tested in a short period.关键词
