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…
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.…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
Thermal Resistance - Definition, Circuit Diagram and Equation: With power transistors, a designer often uses a heat sink to get a high power rating for the transistor. As already mentioned,…
Two Supply Emitter Bias Circuit: From the stability point of view, this two supply emitter bias circuit is the best of all already discussed circuits, but it has one drawback…
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…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high…
Frequency Stability of Oscillator: An oscillator having initially been set at a particular frequency does not maintain its initial frequency, but instead drift and wander about in frequency, sometimes uniformly…
