Abstract

This paper presents a new electronically tunable differential difference current conveyor (DDCC) using operational transconductance amplifiers (OTAs). Unlike conventional DDCC, the proposed DDCC offers current gain between z- and x-terminal that can be controlled electronically by bias currents. The DDCC-based OTA can be investigated both simulation and experiment tests. The proposed DDCC is used to implement a quadrature oscillator to confirm workability.
