A new controlled current conveyor operating in class A and implemented using a low-cost industrial BiCMOS 0.8 µm process is described. Its electrical characteristics (voltage and current transfers, parasitic impedances) have been measured. With a bias current of 500 µA and supplied under ±2.2 V, the measurement results show that the circuit exhibits very large –3 dB bandwidths: from DC to 4.5 GHz for the voltage transfer (between Y and X) and from DC to 2 GHz for the current transfer (between X and Z).
