Abstract: The paper presents a sub-volt design of highly precise second-generation current conveyor (CCII ± ) using Miller compensated Operational Transconductance Amplifier (OTA) designed using bulk driven quasi-floating gate (BDQFG) MOSFET. The bulk-driven approach help in working of proposed CCII ± at low supply voltage. Moreover, followed BDQFG technique results in improves the transconductance and frequency response of the circuit over standalone bulk-driven technique. The proposed CCII ± operates at ± 0.4V. Other performances which encourage its wide applicability are in terms of high current range and high bandwidth. The analysis of proposed current conveyor is carried in 0.18 μmtwin-well CMOS technology using HSpice.
