Class D Power Amplifiers - Circuit Diagram, Operation and Applications: Historically, audio amplifiers have been configured as class A, class B or class AB and the art of design is…
Operational Transconductance Amplifier (OTA): The operational amplifiers considered up to this point have been voltage amplifiers. The input signal is a voltage and the output signal is a voltage. Another…
What is Tristate Logic or Three State Logic Circuit? Tristate Logic or Three State Logic Circuit - In normal logic circuits there are two states of output, either low or…
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,…
Explain Transistor Current Components: The various transistor current components which flow across the forward-biased emitter junction and reverse biased collector junction are indicated in Fig. 10.11. The current flowing into…
Logic Circuit in Static Relay: The concept of Logic Circuit in Static Relay can be better understood by considering the logic operations performed by the devices rather than the actual…
Silicon Controlled Rectifier Principle Operation: Silicon Controlled Rectifier Principle Operation (SCR) consists of four layers of semiconductor material, alternately p-type and n-type as illustrated in Fig. 19-1(a). Because of its…
Diesel Electric Traction System: Because of high initial cost, electric traction is justified only where there is sufficient volume of traffic. Diesel Electric Traction System is preferable where the traffic…
