dc.description.abstractThis thesis is focused on the design and implementation of the readout circuit for MEMS oscillating accelerometer due to the fact that it can achieve state-of-the-art noise performance and much larger full scale range simultaneously. Complete phase noise model is proposed to analyze the noise contributions of 1/f&179 and 1/f&178 phase noise. Based on the noise model, two accelerometers are implemented for high performance and ultra-low power applications. The first accelerometer investigates the noise contributions in amplitude path and suppresses the 1/f&179 noise, and optimizes the sense interface to attenuate the 1/f&178 noise. The second accelerometer is optimized for power consumption without significant performance deterioration. Both designs achieve state-of-the-art noise performance while providing much larger full scale range. An on-chip frequency measurement circuit is also proposed to digitize the analog frequency for interface purposes.
