Abstract

This paper presents a novel current-controlled current conveyor transconductance amplifier (CCCCTA). The design considerations is realized in CMOS technology based on the AMS´s 0.35 μm CMOS process. The performances are examined through HSPICE simulations. The proposed element consists of a balanced differential-pair CCCII circuit and operational transconductance amplifier (OTA). It provides less number of MOSFETs, reducing requirement of large bias current. Wide-band of current transfer range and less power consumption are also obtained.
