Abstract

The MMAS40G is a highly miniaturized accelerometer developed for automotive applications. This two-chip system includes a capacitive micromechanical silicon chip and an associated CMOS integrated circuit for interfacing and signal conditioning each with a die size of 130 mil ². The accelerometer requires a 5 V power supply and consumes 3.8 mA of quiescent current. The frequency response is flat from dc to 400 Hz and exhibits a 4-pole rolloff beyond 400 Hz. A noise analysis of the circuitry is presented herein
