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,…
DC Equivalent Circuit of Transistor: DC Equivalent Circuit of Transistor - In the common base circuit, the emitter diode acts like a forward biased ideal diode, while collector diode acts…
Transistor as an Amplifier - Circuit Diagram and Its Workings: The main utility of a transistor lies in its ability of amplifying weak signals. The weak signal is applied at…
Transistor Circuit Configurations (CB, CE, CC): As already mentioned, a Transistor Circuit Configurations is a three-terminal device (having three terminals namely emitter, base and collector) but we require four terminals—two…
Transistor Terminals (Emitter, Collector and Base): As mentioned already, transistor is a single crystal in which there are two P-N junctions, as shown in Fig. 10.1. The idea behind is…
What is Cathode or Emitter and Types of Cathode? The substance employed for electron emission is called a cathode or emitter. It is an essential part of an electron tube.…
Smoothing Circuits: The rectified a.c. consists of a series of undirectional half waves of current or voltage. It is generally desirable to smooth this output. The various filters used for…
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…
