Realization of Simple Electronic Functions Using EXCCII

The paper presents a simple circuit for the realization of two digital modulation schemes: BPSK and ASK simultaneously, with the advantage of high input impedance at the signal input nodes and use of grounded resistors. The new circuits are based on the use of extra-X current conveyor. Detailed analysis is given and circuit verification is carried out through simulations with a supply voltage of ±1.25V and 0.25μm CMOS parameters to support the proposed circuit. Nonideal study is also given. An extended application of the circuit in realizing precision half-wave and full-wave rectifiers is further proposed by incorporating a simple modification to the proposed topology. The new proposed CMOS compatible electronic circuits enrich the utility of extra-X current conveyor for realizing diverse electronic functions.
