Abstract This paper presents a novel One-shot pulse Generator Circuit, which is composed of only one differential voltage current conveyor (DVCC) as the active element. The application circuits utilizing the DVCC are introduced and implemented. Only one DVCC and two resistors and one capacitor are required to construct every circuit. Each circuit is able to provide a pulse-shaped response having changeable width via a positive-edge triggered signal. The first one is a general one-shot pulse generating circuit. The second design can reduce the recovery time after applying triggered signals. Is-Spice is the simulation software to simulate every model. To fabricate the models commercially available ICs (AD844AN) and passive elements are required. Program and experimental outputs satisfy theoretical results.

1 Introduction One-shot pulse generators are widely used in instrumentation, communication, phase-locked loop circuits, power conversion control circuits, and signal processing applications [1]. Generally, one-shot pulse generator circuit consists of operational amplifier basically in voltage comparator mode, one capacitor, and three resistors [2] as shown in Fig. 1. This paper presents a novel one-shot pulse Generator Circuit composed of only one DVCC as active element. The application circuits utilizing the DVCC are introduced and implemented. The first one is a general one-shot pulse generating circuit. The second design can reduce the recovery time for triggering signals. Due to wide popularity of DVCC-based application circuits in the present era having larger width of the band, greater exactness, higher active range, Amit Bhattacharyya (&) Department of Electronics and Communication Engineering, Haldia Institute of Technology, Haldia, WB 721657, India e-mail: [email protected] © Springer Science+Business Media Singapore 2017 R.

and ease of fabrication [3–6] over traditional operational amplifiers, the presented one-shot pulse generator circuit is more applicable than the traditional designs to DVCC-based circuit systems. The proposed model has a number of advantages over the traditional design due to following reasons: (1) Number of active devices used in the model are less or same. (2) Most of the passive components are grounded rather than floating structure to obtain the advantages of IC fabrication techniques and enhanced parasitic properties. (3) Obtained operating frequency is higher than OPA-based structure. (4) The design can shorten the recovery time for triggering signals. (5) Temperature sensitivity is less. (6) Applicability in fully DVCC-based systems increases (Fig. 1
