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…
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…
Effect of Internal Transistor Capacitance: As we know already that at high frequencies, the coupling and bypass capacitors act as short circuit due to their low reactance and hence the…
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…
Applications of FETs (Field Effect Transistors): Applications of FETs - FET has a very high input impedance (100 MΩ in case of JFETs and 104 to 109 MΩ in case of…
Generalized FET Amplifier Circuit: The analysis of a common source amplifier with a source resistance RS, a common gate amplifier and a common drain amplifier at low frequencies may be…
Fixed Bias Circuit Diagram - Advantages and Disadvantages: Fixed Bias Circuit Diagram shown in Fig. 12.5 uses two batteries VBB and VCC. The battery VBB gives potential to the base…
Bias Stability Factor of Transistor: Bias Stability Factor of Transistor - Only the fixing of a suitable operating point is not sufficient but it is also to be ensured that…
