Differential Voltage Current Conveyor Based One-Shot Pulse Generator Circuit Implementation


  • Department of Electronics and Communication Engineering Haldia Institute of Technology, Haldia – 721657, West Bengal, India


Background/Objectives: To design and analysis of One-shot pulse Generator Circuit, which is composed of only one Differential Voltage Current Conveyor (DVCC) as the active element. Methods/Statistical Analysis: Two 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 after applying triggered signals. Is-Spice is the simulation software to simulate every model. Commercially available ICs AD844AN and passive elements are required for circuit implementation. Findings: The effectivity of the projected circuits is examined as programme and experimental outputs satisfy theoretical results. Simulated and measured waveforms of Vtrg, Vo, and VC for two projected models with T = 1 ms are shown and it is clearly observed, that even the design parameters are same; the second proposed circuit is able to reduce the recovery time. The measurements show that recovery time Tr is 281 μs for the first proposed model, and Tr is 21.3 μs for the second proposed model. Applications/Improvements: The projected models provide new applications for the DVCC based systems. They have wide applications in the instrumentation, measurement, and communication systems and phase-locked loop circuits.
