mechanisms. As most of latest mobile phones are capable of charging from Universal Serial Bus (USB) we decided to design our circuit capable of supplying standard USB voltage and current rating. The circuit consists of a piezoelectric buzzer‚ a rectifier with a storage capacitor‚ an amplifier section‚ regulator and a switching mechanism that controls the energy flow into the battery. Experimental results showed that the method is feasible for practical use. 1 TABLE OF CONTENTS EXECUTIVE SUMMARY

I. Diode and Diode Application 1. Diodes 2. Rectification 3. Power supply filter 4. Applications of diodes ← Signal rectifier ← Diode gate ← Diode clamps ← Limiter Diodes Some elements are linear (resistors‚ capacitors‚ inductors)‚ which means that doubling the applied signal (let us say a voltage) produces a doubling of the response (let us say a current). They are also passive – they do not have built-in source of power. They are two-terminal devices‚ (which

CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless
