Low Frequency Response of BJT Amplifier: For analysis, we will consider the loaded voltage-divider BJT bias configuration. But the results can be applied to any configuration. For the network shown in Fig. 15.14 the capacitors…
Millers Theorem and its Equivalent Circuit: Millers theorem - Consider an arbitrary circuit shown in Fig. 15.13(a). As part of a larger network that is not shown, we have isolated two circuit nodes, labelled 1…
What is Frequency Response of an Amplifier? The voltage gain of an amplifier varies with signal frequency due to the effect of variations in circuit capacitive reactance with signal frequency on the output voltage. The…
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…
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.…
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,…
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…
What is Single Stage Transistor Amplifier? - Circuit Diagram and its Workings When only one transistor with associated circuit is used for increasing the strength of a weak signal, the circuit is known as single…
Difference between NMOS and PMOS: The Difference between NMOS and PMOS is given below 1. P-channel is much easier and cheaper to produce than the N-channel device. 2. The drain resistance of P-channel MOSFET is…
Difference between JFET and MOSFET: The Difference between JFET and MOSFET are quite similar in their operating principles and in their electrical characteristics. However, they differ in some aspects, as detailed here : 1. In…
