Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output,…
Hartley Oscillator using Transistor Analysis: The transistor Hartley oscillator is as popular as Colpitt's oscillator and is widely used as a local oscillator in radio receivers. The circuit arrangement is…
Tuned Base Oscillator - Definition and Working Principle: When a parallel tuned L-C circuit is placed in the base-to-ground circuit, the oscillator is known as the tuned base oscillator. The…
Tuned Collector Oscillator - Definition, Working and Equation: The basic circuit of a tuned collector oscillator is shown in Fig. 21.7. It is called the tuned collector oscillator, because the…
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…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
What is Dual Power Supply? -Circuit Diagram and its Workings? Many discrete and ICs need bipolar (dual power supply or ± V) supplies. This can be easily accomplished with two…
Fixed Positive Voltage Regulators: The series 7800 regulators provide eight voltage options, rangÂing from 5 to 24 V, as indicated in Table 43.2. These ICs are designed as fixed voltage…
