Let's start with thesymbol of transistorsso that you can identify them in a circuit. The below diagram shows the symbols of the twotypes of transistors. The one on the left is thesymbol of the PNP transistorand the one on the right is thesymbol of the NPN transistor. As I said, you...
The word “transistor” comes from “Transfer” and “Resistor,” describing a BJT’s operation—transferring an input signal from a low-resistance circuit to a high-resistance circuit. This type of transistor is made from semiconductors. Transistors are used in the construction of Integrated Circu...
The Field Effect Transistor In the Bipolar Junction Transistor tutorials, we saw that the output Collector current of the transistor is proportional to input current flowing into the Base terminal of the device, thereby making the bipolar transistor a “CURRENT” operated device (Beta model) as a ...
I'll add that in discrete multi–transistor packages, e.g., CA3046 etc., I find it preferred practice to show them as individual discrete devices with an envelope representation, as this is the most convenient way of drawing the circuit diagrams – and annotate e, b and c with the packa...
BJT Transistor theory Power Calculation and Efficiency It is important to be able to calculate the power characteristics of a transistor circuit. This includes both the input and output signal power, the power gain of the circuit, the efficiency and the power dissipation on the transistor. ...
A slight improvement is achieved with the following circuit, where the transistor is configured in collector-feedback bias. The negative feedback produced through Rb ensures that the DC operating point always remains in the active region.

A bipolar junction transistor includes a three-terminal device so it can be connected to a circuit in three possible ways through one terminal being common between others which means one terminal in between input as well as output is common. Every connection simply responds in a different way to...
Figure 1 shows such a BJT differential amplifier circuit made of two BJTs (Q1and Q2) and two power supplies of opposite polarity, VCCand –VEEwhich uses threeresistorsamong which two are the collector resistors, RC1and RC2(one for each transistor) while one is the emitter resistor REcommon ...
There are two kinds of transistors namelyPNP and NPN. The main difference between BJT and MOSFET is their charge carriers. In the PNP transistor, P stands for positive and the majority charge carriers are holes whereas in the NPN transistor, N stands for negative and the majority charge carrie...
