Abstract :
A new CMOS electronically tunable current conveyor (ECCII) based on programmable current amplifier circuit is presented, with low power voltage(±1.2V) and continuous programmable current gain and highly linear wide tuning range and high output impedance at terminal Z. The current transfer ratio of the conveyor can be accurately controlled by the ratio of the DC bias currents. HSPICE simulation results using 0.35-μm CMOS process model confirm the expected good performance of the proposed ECCII in terms of linearity, frequency response, noise, tunability, and power consumption.
