Transistors Amplifiers Common Emitter Amplifier ("Simplified") l What's common (ground) in a common emitter amp? The emitter! The emitter is connected (tied) to ground usually by a capacitor. To an AC signal this looks like the emitter is connected to ground. • What use is a Common Emitter Amp? Amplifies the input voltage (the voltage at the base of the transistor). The output voltage has

Q point = Quiescent point, resting point. When the amplifier circuit is left undisturbed, it is like in meditation, Q point is all quiet. But when a signal is applied to the amplifier, this Q point starts moving up and down on the load line , the extent of movement depending on the amplitude of the

Transistor Biasing Circuit (Q point and dc load line) 2 Objective • To understand the concept of dc biasing of a transistor for linear operation. • To determine Q point and dc load line. 3 Introduction • For the transistor to properly operate it must be biased. There are several methods to establish the DC operating point. We will discuss some of the methods used for biasing transistors

1. Discuss about the DC load line and Q point. (OR) What

These voltages and currents are called quiescent values which determine the operating point or Q-point for the transistor. The process of giving proper supply voltages and resistances for obtaining the desired Q-Point is called Biasing. The circuits used for getting the desired and proper operating point are known as biasing circuits. To establish the operating point in the active region
