Voltage to current converter is mostly used to transmit signals over a long distance to a control circuit. The most important reason behind it is that while traveling a long distance due to the internal resistance of the wire the voltage gets reduces. if there is a very small signal then it may get lost. […]

Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
Current to Voltage Converter(I to V)
A current to voltage converter circuit produces output voltage with respect to input current. An I to V converter is used to convert varying current into equivalent output voltage. This circuit is very much useful when the measuring instrument can measure only voltages not the current and we want to measure the output current. The […]
Gunn Diode Working Principle VI Characteristics & Applications
Gunn diode operates on the Gunn effect which is named after its inventor J.B. Gunn. He discovered the periodic variation of current in a GaAs (gallium arsenide) rod in 1963. The microwave device that operates on the principle of transfer of electrons is called as Gunn diode. This is one of the diodes used as […]
VI Characteristics of IGBT and it’s Working Principle
The VI characteristics of IGBT is as shown in Figure. In the forward direction, they are similar to those of bipolar transistors. The only difference here is that the controlling parameter is the gate to source voltage Vgs and the parameter being controlled is the drain current. The working principle of IGBT is based on […]
IGBT-Insulated Gate Bipolar Transistor its Working and Applications
An insulated-gate bipolar transistor (IGBT) is a three-terminal semiconductor device it is a hybrid of MOSFET and BJT for high efficiency and fast switching. The power BJT has the advantage of low on state power dissipation, but it cannot be switched at faster rates due to longer turn-off time, whereas MOSFETs have a very high […]
Triac Working, Structure, VI Characteristic and Application
A Triac is a bidirectional device it allows current to flow in both the directions. here we will discuss Triac working and vi characteristics, In the SCR family, after the SCR, Triac is the most widely used device for power control. Triac is a three-terminal device, with the terminals named as main terminals 1, 2 […]
