LM340 Series Voltage Regulator: This LM340 Series Voltage Regulator is typical of the three-terminal voltage regulators. The block diagram is shown in Fig. 43.27. The built-in reference voltage Vref drives…
Three Terminal IC Voltage Regulators - Block Diagram: The latest generation of IC voltage regulators has devices with only three pins: one for the unregulated input voltage, one for the…
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…
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.…
Basic Controls of CRO: Number of controls are required to be provided on a panel of CRO to facilitate its proper functioning. Intensity control is provided for adjustment of brightness…
Transistor Hybrid Model: The basic assumption in arriving at a transistor linear model or equivalent circuit is that the variations about the operating or quiescent point are small and, therefore,…
Hybrid Parameters of Transistor or h Parameters and Hybrid Model: A box representing a two-port network is illustrated in Fig. 11.1. The terminal behavior of a two-port device may be…
