This paper proposes a dual-mode controlled pulse width monostable multivibrator used for analogue signal processing applications that employs two differential voltage current conveyors (DVCCs), four passive components and an analogue switch. Unlike the traditional operational-amplifier-based monostable multivibrators, the proposed circuit contributes a dual-mode controlled scheme for adjusting the output pulse width through a voltage source and a grounded resistor. This paper discusses several previous designs and presents the circuit operations, related governing formulas, non-ideal effect problems, design considerations, and experimental examples of the proposed circuit. A prototype circuit was implemented, and commercially integrated circuits and discrete passive components were used to execute the experimental tests. The features of the proposed circuit are discussed, and the experimental results indicated that the circuit is feasibly used in dual-mode controlled pulse width for the output pulse and were consistent with those of the theoretical analyses.
