CMOS ECCCII with Linear Tune of Rx and Its Application to Current-mode Multiplier

Chaiwat Sakul


In this paper present CMOS second-generation current-controlled-current-conveyor based on differential pair operational transconductance amplifier. Its parasitic resistance at x-port can be linearly controlled by an input bias current. Therefore, a proposed building block is called electronically tunable second-generation current-controlled-current-conveyor (ECCCII). The application presents 2-quadrant and 4-quadrant current-mode signal multiplier circuits. Characteristics of the proposed ECCCII and its application are simulated by the PSPICE program and they are in agreement with the theory.
