Noise in Amplifiers and its Types: Noise in Amplifiers – Noise is any kind of unwanted signal that is not related to the input. Any electronic component produces a certain amount of noise. When these components are assembled to build a device or circuit and if a signal is supplied to it, the noise produced […]

Explain Distortion in Amplifier? | Types of Amplifier Distortion: Under ideal conditions, amplified output signal must have exactly the same waveform as the input signal. But in practical amplifiers, this ideal condition is never achieved. Some changes in the waveform may take place in addition to the increase in the amplitude. Such a change is

Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output, frequency range of operation, input, the number of stages used, coupling methods, mode of operation (biasing conditions) and on the basis of bandwidth. Based on

Phase Reversal in Single Stage Transistor Amplifier: In a common emitter configuration, the output voltage increases in the negative direction when the input signal increases in the positive direction and vice versa. This is called Phase Reversal in Single Stage Transistor Amplifier and causes a phase difference of 180° between the input signal voltage Vin
