The system contains the MEMS cantilevered flow sensor, the signal processing circuit and the digital conversion circuit, and they are integrated into a single chip. A DC offset calibration technique has been proposed to eliminate the offset voltage caused by the MEMS cantilevered flow sensor. Two versions of MEMS cantilevered flow sensors with different designs are implemented and their sensitivities are compared. This chip was fabricated by using Taiwan Semiconductor Manufacturing Company (TSMC) 0.35μm CMOS/MEMS 2P4M 3.3V mixed-signal polycide process and MEMS post process. The die area of this chip is 1.797x 2.353 mm2. The system power consumption is 6.31 mW containing the sensor power consumption. Chia-Ling Wei 魏嘉玲 2014 學位論文 ; thesis 73 en_US
