In this study a low supply voltage CMOS pseudo differential operational trans conductance amplifier (OTA) with CMFF and HD3-FF to improve CMRR and THD is proposed. Common mode rejection ratio (CMRR) is improved by using the common mode feed forward (CMFF) technology and the THD is simulated result of improved by using a HD3 feed forward (HD3-FF). The proposed OTA shown the CMRR is 68.6dB and the THD...
CMOS pseudo differential operational transconductance amplifier (OTA) has been proposed in this study. It can operate with significantly low supply voltage and provides respectable high output impedance. Besides, it enhances the common mode rejection ratio (CMRR) by using a special common mode feed forward (CMFF) technology. The chip has been manufactured in a 0.35 ??m-CMOS technology. The simulation...
