Abstract :
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.
