英文摘要	A programmable readout circuit for capacitive accelerometer is presented. The inequality of initial capacitance of sensor's differential capacitor pair is properly compensated. The gain of CSA and the cut-off frequency of LPF are both adjustable. To lower noises, amplifier of CSA is carefully designed. Its equivalent input noise density is 12.7nV/root Hz. A rail-to-rail buffer is chosen to enlarge the measurement range. EEPROM instead of pads is exploited, which saves about 33 percent of the layout area.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000304037500040&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Electrical & Electronic; Physics, Applied; CPCI-S(ISTP); 0
