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…
IC Voltage Regulators: IC voltage regulators are versatile and relatively inexpensive and are available with features such as a programmable output, current-voltage boosting, internal short-circuit current limiting, thermal shutdown, and…
