A 170µW readout IC for a capacitive MEMS acceleration sensor was implemented in a 1.5V 0.13µm CMOS for high-end medical motion sensing applications. The accelerometer achieves a 45µg/vHz noise floor and a dynamic range larger than 87dB for a 400Hz bandwidth. Power reduction is achieved by introducing reset and common-mode feedback circuit techniques based on a non-unity-gain feedback configuration.
