Photon Absorption Coefficient: Photon Absorption Coefficient - When light falls on a semiconductor, the photons may be absorbed or they may propagate through the semiconductor depending on the photon energy…
Classification of Pulse Signals: The Classification of Pulse Signals are divided into four categories, namely Periodic signals. Aperiodic signals. Random signals. Continuous and Discrete Signals 1. Periodic Signals: Periodic signals…
Miller Sweep Circuit and Miller Bootstrap Sweep Circuit: The basic R-C sweep circuit is shown in Fig. 30.134, in which opening of switch S provides sweep voltage, as already explained…
Uninterruptible Power Supply (UPS) - Block Diagram and its Workings: Uninterruptible Power Supply (UPS) - Most of us take the mains ac supply for granted and use it almost casually…
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…
Regulated and Unregulated Power Supply: Almost all electronic devices used in electronic circuits need a dc source of power to operate. The source of dc power is used to establish…
What is Emitter Coupled Logic (ECL) Circuit? Emitter coupled logic (ECL) is the fastest of all logic families and, therefore, is employed in applications where very high speed is essential.…
What is Transistor Transistor Logic (TTL) Circuit? Texas instruments introduced transistor transistor logic (TTL), a widely used family of digital devices in 1964. It is fast, inexpensive and easy to…
