Cascode Amplifier or CE-CB Configuration: The CE-CB configuration (usually referred to as cascode amplifier) is shown in Fig. 16.44. Figure 16.44 shows a cascode configuration with a common-emitter (CE) stage…
What is Low Frequency Compensation? The coupling or blocking capacitor tilts the amplifier response for step input. In Fig. 16.28, if a high value of resistance Rd is added in…
n Stage Cascaded Amplifier: As already discussed, several amplifier stages are usually cascaded to increase the overall voltage gain of the amplifier. However, sometimes cascading is done to obtain the…
What is Multistage Amplifier? - Types, Block Diagram and Analysis Amplifiers that produce voltage, current, and/or power gain through the use of two or more stages are called multistage amplifiers.…
Miller Effect in Amplifier Frequency Response: According to this effect, when viewed from the input base terminal of the CE-connected transistor the capacitance Ccb appears as (1 - Av)Ccb i.e., it is…
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…
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…
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…
