A Study of Butterworth Filter Based on Operational Transconductance Amplifier

RenuSahu, Zoonubiya Ali, BalramTimande

This study presents different structure of operational transconductance amplifier (OTA) which is an integral part of continuous time channel selection filter. It was observed that to enhance the linearity and to reduce the third order harmonic distortion, linearity schemes are used however most of those techniques present important drawback such as reduced effective transconductance, significant power consumption, limited frequency response, increased noise level. It presents new linearity scheme source degeneration and auxiliary differential pair technique by which the linearity can be increased without sacrificing other important parameters such as noise level, power efficiency and frequency response which is better than other schemes.
