摘要

提出了一种脉冲宽度调制输出的集成电容式传感器接口电路。该电路基于原始结构，通过斩波调制实现偏移和低频噪声消除。在使用0.32 mum/ 3.3 V CMOS器件设计的原型上进行的电学模拟表明，该方法对温度的灵敏度低于10 ppm/℃，功耗为66 muW。

A low power capacitance to pulse width converter for integrated sensors

An interface circuit for integrated capacitive sensors with pulse width modulated output is presented. The circuit is based on an original architecture implementing offset and low frequency noise cancellation by means of chopper modulation. Electrical simulations, performed on a prototype designed using 0.32 mum/ 3.3 V CMOS devices, showed that a sensitivity to temperature lower than 10 ppm/degC with a power consumption of 66 muW can be obtained with this approach.
