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…
Transistor Series Voltage Regulator or Emitter Follower Voltage Regulator: A simple series voltage regulator using an NPN transistor and a zener diode is shown in Fig. 43.5. This circuit is…
Octal Number System (Definition, Conversions & Examples): The number system with base (or radix) eight is known as the octal number system. Although we can use any eight digits, it…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip,…
Varistors or Voltage Dependent Resistors (VDRS): Varistors, also called the voltage dependent resistors (VDRs), show a high degree of nonlinearity between their resistance value and the applied voltage. They are…
