Classification of Amplifiers: In the Classification of Amplifiers, the transistor amplifiers may be classified in several ways such as on the basis of transistor configuration used, active device used, output,…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
Advantages and Disadvantages of JFET: Junction field-effect transistors combine several merits of both conventional (or bipolar) transistors and vacuum tubes. Some of these advantages and disadvantages of JFET are enumerated…
What is Oscillator? - Types of Oscillators: An oscillator is the basic element of all ac signal sources and generates sinusoidal signals of known frequency and amplitude. It is one…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip,…
Optoelectronic Devices Articles: Light Units: The total light energy output, or luminous flux (Φs), from a source can be measured in milliwatts (mW) or in lumens (1m), where 1 Im…
Optocoupler Circuit Operation: An Optocoupler Circuit Operation (optoelectronic coupler) is essentially a photo-transistor and an LED combined in one package. Figure 20-35(a) and (b) shows the typical circuit and terminal…
