摘要

提出了一种用于三轴电容式加速度计的CMOS接口。该电路实现了一种创新的读出方法，使得功耗比传统方案低得多，这也归功于降低了电路的复杂性。在2.5 V标称电源电压下，整个接口的总功耗为175 muW。

A low power CMOS interface circuit for three-axis integrated accelerometers

A CMOS interface for three-axis capacitive accelerometers is presented. The circuit implements an innovative readout approach which allows to obtain a power consumption much lower than traditional schemes, thanks also to the reduced circuit complexity. A total power consumption of 175 muW at the nominal supply voltage 2.5 V is obtained for the entire interface.
