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…
