"Sharpening Skills..... Serving Nation" Active Filter Design Using OTA Realization

Abstract — The OTA is an amplifier whose differential input voltage produces an output current. Thus, it is a voltage controlled current source. Operational transconductance amplifier is one of the most significant building-blocks in integrated continuous-time filters. We show that the operational transconductance amplifier (OTA), as the active element in basic building blocks. In this paper Low pass filter is realized using OTA realization. SPICE simulation showed that they are suitable for real time application. Keywords- OTA, CMOS IC Design, OTA-C Low Pass filter, cadence, VCCS
