Transistor Clipper Circuit and Waveforms: Transistor Clipper Circuit - The transistor has two pronounced nonlinearities—one occurs when the transistor passes from cutin region to the active region and the second…
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…
Constant Voltage Transformer (CVT) - Construction and Working Principle: With the popularization of PCs, the constant voltage transformers (CVTs) have also become equally popular. The Constant Voltage Transformer is simply…
Characteristics of Regulated Power Supply: The quality of power supply depends on different factors such as its load voltage, load current, voltage regulation, source regulation, output impedance, ripple rejection etc.…
Basic Controls of CRO: Number of controls are required to be provided on a panel of CRO to facilitate its proper functioning. Intensity control is provided for adjustment of brightness…
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 Action : Operation of PNP Transistor: Transistor action - Transistors of both types (P-N-P and N-P-N) behave exactly in the same way except change in biasing and majority carriers.…
