Implementation of Dual Hysteresis Mode Flip-Flop Multivibrator Using Differential Voltage Current Conveyor

Abstract

Background/Objectives: Implementation and analysis of dual hysteresis mode flip-flop multivibrator circuit consisting of merely one differential voltage current conveyor (DVCC) as dynamic component. Procedures/Approach: Projected dual hysteresis mode flip-flop multivibrator circuit consists of a DVCC, two resistors R 1 and R 2, and a double pole double throw dual in-line package (DPDT DIP) mechanical type switch. Top and bottom saturation levels of the flip-flop multivibrator can be set using passive components. Real structure in design of projected model describes operation of the circuit. Projected design is simulated by Spice as simulation tools. Easily accessible IC AD844AN and passive components are necessary for circuit construction. Outcomes: Actuality of the planned model is scrutinized as measured and simulation results well agree with hypothetical result. Simulation and measurement results of V o–V in transfer characteristic curves for clockwise and counter clockwise mode with an operating frequency of f = 1 kHz are shown. It is observed that edge voltages for the simulated and measured results are adjacent to the projected values V TH = 5 V, V TL = −5 V, and the projected flip-flop multivibrator circuit is able to fulfill the dual hysteresis action surrounded by alike design criteria. Projected model provides new presentation for the DVCC founded systems. DVCC has extensive presentations in the area of communication systems, signal processing field especially processing of electrocardiogram signal (ECG), instrumentation, and measurement systems.
