Bipolar junction Transistors 1. Introduction The Bipolar Junction Transistor (BJT) is one of the most important solid-state devices. It is a two-junction‚ three-terminal device‚ in which the current flow properties of one p-n junction can be modulated by another p-n junction. The structure can be either p-n-p or n-p-n. The three terminals are called emitter‚ base and collector. The circuit symbols of the two types of BJT are shown in Fig.1. The arrow on the emitter signifies the direction of

Experiment No: 9 Date: COMMON BASE CHARACTERISTICS OF A TRANSISTOR Aim: To plot the input and output characteristics of an NPN transistor in common base configuration and calculate various parameters. Components and Equipments Required: Transistor‚ voltmeters‚ ammeters‚ rheostats‚ dc sources‚ breadboard and CRO. Theory: In CB configuration‚ the base of a transistor is common to input and output circuits. Input voltage is applied between emitter and base and output is taken across collector and

use of transistor for designing logic gates. Further down in the course we will use the same transistors to design other blocks (such as flip-flops or memories) Ideally‚ a transistor behaves like a switch. For NMOS transistors‚ if the input is a 1 the switch is on‚ otherwise it is off. On the other hand‚ for the PMOS‚ if the input is 0 the transistor is on‚ otherwise the transistor is off. Here is a graphical representation of these facts: When a circuit contains both NMOS and PMOS transistors we say

design‚ the number of transistors is reduced to decrease the area. The number of clocked transistors of the devised flip-flop is also reduced to minimize the power consumption. As compared to the other state of the art single edge triggered flip-flop designs‚ the newly proposed design is the best energy efficient with the comparable power delay product (PDP) having an improvement of up to 61.53% in view of power consumption. The proposed flip-flop also has the lowest transistor count and the lowest
