Design and implementation of monostable multivibrators employing differential voltage current conveyors

In this paper, two novel application circuits utilizing the differential voltage current conveyor (DVCC) are introduced and implemented. To the best knowledge of authors, this is the first reported monostable multivibrators employing DVCC device. Each presented circuit is constructed by single DVCC as the basic active building block together with a few passive components. Both of them can be operated via a positive-edge triggering signal to generate a pulse waveform with an adjustable width. The first one is a general monostable circuit. The second design is an improved construction, which shortens the recovery time for applying the consecutive triggering signals. The circuit operations are first described and then the non-ideal issues and design considerations of the proposed circuits are discussed. To demonstrate their feasibility, the presented circuits are simulated using circuit simulation program Is-Spice. Available commercial ICs and discrete components are used to implement the prototype circuits. Simulation and experimental results agree well with the theoretical analysis.
