Harmonic Distortion in Power Amplifier - Waveform and Derivation: Harmonic Distortion in Power Amplifier - Output signal variations of less than 360° of the signal cycle are considered to have…
Transformer Coupled Class A Power Amplifier: Transformer Coupled Class A Power Amplifier also sometimes referred to as single ended power amplifier. The term "single ended" (denoting only one transistor) is…
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…
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…
Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
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…
FET Biasing Methods - Fixed Bias, Self Bias, Potential Divider Bias and Current Source Bias: Unlike BJTs, thermal runaway does not occur with FETs. However, the wide differences in maximum…
Selection of Oscillator: While in the Selection of Oscillator for a particular application, the following particulars are to be considered. Frequency Range: The oscillator selected for a particular application should…
