英文摘要	This paper presents a MEMS gyroscope control system based on a band-pass continuous-time sigma-delta modulator (Sigma Delta M). Compared with a low-pass discrete-time based solution, it enables a circuit implementation at a much reduced sampling frequency; therefore can be easily implemented in hardware using standard off-the-shelf electronic components. System level simulations using Simulink show the proposed sixth order electromechanical Sigma Delta M can achieve a high SNR of 100dB at a full scale input signal of 200 degrees/s. Measurement of the power spectral density of the output bitstream reveals a noise floor of -90dBV/Hz(1/2). The prototype is tested on a rate table with an angular signal, verifying that the principle of the approach using an electromechanical band-pass Sigma Delta M control system for a MEMS gyroscope.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000287982100194&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; Instruments & Instrumentation; EI; CPCI-S(ISTP); 0
