Abstract

This paper presents a design of low power low voltage positive second generation current conveyor (CCII) which is based on Miller compensated Operational Transconductance Amplifier (OTA). The OTA realisation is carried out using low power techniques bulk-driven (BD) and bulk-driven quasi-floating gate (BDQFG) for a comparison of aforementioned techniques. The use of bulk-driven approach facilitates the proposed CCII design operable at sub-volt supply. Furthermore, CCII realisations using BD and BDQFG have been done so as to have a fair comparison of advantage of using BDQFG over BD in terms of improving transconductance and frequency response. The proposed CCII operates at 0.4V. The complete analysis has been carried out in 0.18 ?mCMOS technology with the help of HSpice simulator.
