The transistor is the fundamental building block of computers ,  There are two types of transistors that are in use today and they  are the bipolar transistor and the field effect transistor. The bipolar transistor is  bipolar meaning that both electrons and holes are involved in a conduction

Unformatted text preview: process. A bipolar transistor has a base, emitter and a collector electrodes, and is a current controlled device with a low input impedance. This type of transistor is used as an amplifier and is also a key component in high-speed integrated circuits. As for the field effect transistor goes, what it is is a unipolar device, as its conducting process involves only one kind of charge carrier. A field effectr transistor has a gate and a source....
