How miller sweep circuit is work?

The miller circuit is also known as by the name of miller integrator. Above figure shows the circuit of the miller sweep circuit or miller integrator. The transistor Q1 act as a switch and transistor Q2­ is

What is junction field effect transistor (JFET)?

The junction field effect transistors (JFET), is a type of field effect transistor (FET). They are three terminal unipolar solid state devices that can be used as voltage controlled resistors or electronically controlled switch. An N-type JFET


What is a potentiometer? The potentiometers are variable linear resistors that deliver an output voltage representing some function of an applied voltage and shaft position. The smaller variable resistors commonly used in electronic circuits are called as

VI characteristic insulated gate bipolar transistor

The V-I characteristic of an insulated gate bipolar transistor (IGBT) shows the plot of collector current IC versus collector emitter voltage VCE for various values of gate emitter voltage. It is similar to the shape of the

What is voltage regulator?

The voltage regulator is a regulator which is designed to automatically convert voltage into a lower, direct current (DC) and constant voltage. It is mainly used to maintain a constant voltage level. A fluctuating DC voltage may


A transformer is a magnetic component or an electric component which transforms electrical a.c. power from one circuit to another circuit without changing the frequency. It works on principle of mutual inductance. Transformers are capable to of

Difference between Voltage amplifier and Power Amplifier

Voltage Amplifier Power Amplifier In voltage amplifier the amplitude of input A.C signal is small. In power amplifier the amplitude of input A.C signal is large. In voltage amplifier the collector current is low, about 1 mA.
