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

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

Semiconductor devices are extensively used in the field of electronics. A semiconductor is a substance whose resistivity lies between conductors and insulators. Semiconductors have negative temperature co-efficient. The resistance in semiconductors increases with the decrease in temperature and vice versa. The conducting properties of a semiconductor changes, when a suitable ... Read More
