The first bipolar junction transistor was invented in 1947 at Bell laboratories. “Two polarities”is abbreviated as bipolar, hence the name Bipolar junction transistor. BJT is a three terminal device ...

In this tutorial, we will show how, under certain conditions, a PNP transistor is equivalent to a single PN junction with a voltage-current characteristic appropriately shifted on the positive ...

Circuit schematics are crucial for electronics engineers to understand. For the majority of real-world applications, Class A amplifiers offer the lowest distortion, Class B amplifiers the most ...

Based on the knowledge developed in the previous tutorials, we now start the study of this important electronic component. We have thus created a PNP transistor. Figure 1: A PNP transistor. The size ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...
