In electronic circuits, we use an electronic device called operational amplifier (Op-Amp). The operational amplifier is a high-gain multistage differential amplifier. It has two inputs and one output, where the input terminals are named as inverting terminal and non-inverting terminal. The inverting terminal of the Op-Amp is marked with positive ... Read More

A Bipolar Junction Transistor (BJT) is a three-terminal device which consists of two pn-junctions formed by sandwiching either p-type or n-type semiconductor material between a pair of opposite type semiconductors.The primary function of BJT is to increase the strength of a weak signal, i.e., it acts as an amplifier. A ... Read More

A transformer is a static electrical machine that is used to increase or decrease the voltage and current in an AC (Alternating Current) system. Based on construction, the transformers are broadly classified into following two types Core Type Transformer Shell Type Transformer In this tutorial, we will ... Read More

BJTs are three-terminal semiconductor devices used for switching and amplification of signals. MOSFETs, on the other hand, are four-terminal semiconductor devices used for switching applications. Read through this article to find out more about BJTs and MOSFETs and how they differ from each other.What is BJT?BJT stands for Bipolar Junction ... Read More

A transistor can be used as a solid state switch. If the transistor is operated in the saturation region then it acts as closed switch and when it is operated in the cut off region then it behaves as an open switch.The transistor operates as a Single Pole Single Throw ... Read More

An operational amplifier is a three-terminal device consisting of two high impedance input terminals, one is called the inverting input denoted by a negative sign and the other is the non-inverting input denoted with a positive sign. The third terminal is the output of the Op-Amp.Inverting Operational AmplifierIn the inverting ... Read More

A Unijunction Transistor (UJT) is a three-terminal semiconductor device. The main characteristics of UJT is when it is triggered, the emitter current increases re-generatively until it is limited by emitter power supply. Due to this characteristic feature, it is used in applications like switching pulse generator, saw-tooth wave generator etc.Construction ... Read More

Go through this article to find out the important features of BJTs and FETs and how they differ from each other in the way they function.What is BJT?BJT stands for Bipolar Junction Transistor. The BJT is ... Read More

Electric circuits are classified into two main types namely series circuit and parallel circuit based on the arrangement of components in the circuit. A series circuit is one in which the components are chain connected, while a parallel circuit is one in which all the circuit components are connected between ... Read More

A rectifier is an electronic circuit that converts the alternating current (AC) into direct current (DC). The process of conversion of alternating current into direct current is known as rectification. The rectifier consists of semiconductor diodes to perform the rectification.Depending upon the type of conversion of AC into DC, i.e., ... Read More
