CHAPTER 3 Switching Characteristics of Devices

3.1 INTRODUCTION

Most of the semiconductor devices in wave shaping and switching circuit function as electric switches. Several semi conductor devices can be operated as electric switches as they have two functional states ON and OFF. In practical applications, it is necessary to use the Junction diodes, transistor, vacuum tubes, thermionic diodes when diode is forward biased, it acts as a closed switches as its forward resistance is zero. Similarly when diode is reversed biased it act as an open switch as its reverse resistance is very high. When transistor is cut off, it acts as open circuit switch OFF condition. When transistor is saturated it acts a closed circuit switch ON condition. The understanding ...
