What is Transistor ? When a third doped element is added to a crystal diode in such a way that two pn junctions are formed, the resulting device is known as a transistor. The transistor—an entirely new type of electronic device—is capable of achieving amplification of weak signals in a fashion comparable and often superior … Read more

INTRODUCTION TO SEMICONDUCTOR Diode :- Materials such as germanium, silicon, carbon, etc. are not good conductors like copper nor insulators like glass. In other words, the resistivity of these substances lies in between conductors and insulators. Such materials are known as semiconductors. Semiconductors have some useful characteristics and are being extensively used in electronics devices. … Read more

Half Wave Rectifier | full wave bridge Rectifier | Center tapped full wave

What is a Half Wave Rectifier? A half-wave rectifier can be explained as a type of rectifier that only passes one half-cycle of an AC voltage waveform to pass, blocking the remaining half-cycle. Half-wave rectifiers are normally used to convert AC power to DC power, and only require one diode to construct. A simple Half … Read more

Active Filters | Crystal Filters | Ceramic Filters | Surface Acoustic Wave

What Are Active Filters? Active filters are frequency selective circuits that incorporate RC networks and amplifiers with feedback to produce a low-pass, high-pass, bandpass, and bandstop performance. These filters can replace standard passive LC filters in many applications. They offer the following advantages over standard passive LC filters. Gain. Because active filters use amplifiers, they … Read more

Digital to Analog Converters | Analog to Digital Converters

Converters: There are many ways to convert digital codes to proportional analog voltages. However, the most popular methods are the R-2R, string, and weighted current source converters. These are available in integrated-circuit form and are also integrated into other larger systems on a chip (SoC). R-2R Converter The R-2R converter consists of four major sections, … Read more
