Abstract
A multi-channel capacitive readout IC (integrated-circuit) for MEMS (microelectromechanical systems) inertial sensor is presented. A fully differential, chopper-stabilized SC (switched capacitor) 3-channel charge amplifier is designed. A digital demodulator and a decimator are used to prevent problems of conventional analog multipliers. Performance of the fabricated IC is evaluated with MEMS sensing elements.
