Darlington Connected Output Transistors: High-power transistors usually have low current gains, so relatively large base currents must flow into Q2 and Q3 to supply a high load current. This means that the quiescent current through…
What is Core Processor?: What is Core Processor? - The Chip-level Multiprocessor (CMP) or multi-core CPU merges two or more independent cores into a single package integrated circuit, called a die. A processor with two…
RS 232 Interface Modem: In the United States, a standard interconnection between business machine and modem is supplied by the RS 232 Interface Modem. RS 232 Interface Modem has been defined by the Electronic Industries…
What is a Floating Point Number? The real numbers considered so far were represented in what is known as fixed point notation. In such notation, the position of the decimal is fixed for a fixed…
Compensating Network in Op Amp: In op-amps the variations in gain and phase shift with respect to frequency are due to the internal capacitors and stray capacitances, which are due to physical characteristics of semiconductor…
Electronics Engineering Multiple Choice Questions and Answers (MCQs) Part 6: 241. The voltage follower is commonly used as (a) Switch. (b) Isolator. (c) Regulator. (d) None of these. Answer : (b) Isolator. 242. A voltage-to-current…
Hays Bridge Circuit: Hays Bridge Circuit, shown in Fig. 11.23, differs from Maxwell's bridge by having a resistance R1 in series with a standard capacitor C1 instead of a parallel. For large phase angles, R1 needs…
Features of Intel 8279 Programmable Keyboard Display Interface: The Intel 8279 is a general purpose programmable keyboard and display I/O interface device designed for use with Intel microprocessors. The Features of Intel 8279 Programmable Keyboard…
Circuit Breakers Definition: A circuit breaker can make or break a circuit either manually or automatically under all conditions viz., no-load, full-load and short-circuit conditions. This characteristic of the Circuit Breakers Definition has made it…
DC Load Line for FET: The DC Load Line for FET circuit is drawn on the device output characteristics (or drain characteristics) in exactly the same way as for a BJT circuit. Refer to the…
