This project serves as a basis to investigate the performance of a PWM generator circuit. This is due to available PWM generation method cannot cover a wide operation frequency and wide duty cycle range. PWM signal had been used in various application including power system, communication and control systems. Pulse-width modulation (PWM) is a very efficient way of providing intermediate amounts of electrical power between fully on and fully off. A simple power switch with a typical power source provides full power only, when switched on. PWM is a comparatively-recent technique, made practical by modern electronic power switches. This project will focus on PWM generation in high frequency of 1 MHz. The aim of this work is to generate PWM signal at 1 MHz frequency with duty cycle ranging from 30 % to 70 %. During the process, various parameters like duty cycle, rise and fall time, and signal resolution is observed to determine the quality of PWM signal generated. From the findings, this work will determine the suitable conditions that can be implemented in suitable application using this PWM generation technique, intersective method.
