| Summary: | 碩士 === 逢甲大學 === 電子工程所 === 100 === A pseudo differential Operational Transconductance Amplifier (OTA) has been proposed in this research. This OTA can operate at low supply voltage with high linearity. Here, we use two technologies, one of them is common mode feed forward and the other is HD3 feed forward. Simulation results show that the common mode rejection ratio (CMRR) is 68.6dB and third harmonic distortion (HD3) is -66.6dB. This OTA consumes 75.8μW for the power dissipation. The chip has been manufactured in a 0.18μm-CMOS technology. The chip area is 0.69x0.38 mm2.
