Common Emitter Amplifier

The common emitter NPN amplifier circuit is shown in the figure below. The source VBB is applied to the input circuit in addition to the signal. The VBB battery provides the forward bias voltage to the emitter-base junction of the transistor. The magnitude of the forward bias voltage should be such that it should keep …

Transistor as an Amplifier

The transistor raises the strength of a weak signal and hence acts an amplifier. The transistor amplifier circuit is shown in the figure below. The transistor has three terminals namely emitter, base and collector. The emitter and base of the transistor are connected in forward biased and the collector base region is in reverse bias. …

Transistor

Definition: The transistor is a semiconductor device which transfers a weak signal from low resistance circuit to high resistance circuit. The words trans mean transfer property and istor mean resistance property offered to the junctions. In other words, it is a switching device which regulates and amplify the electrical signal likes voltage or current. The …

Binary Addition and Subtraction

The addition and subtraction of the binary number system are similar to that of the decimal number system. The only difference is that the decimal number system consists the digit from 0-9 and their base is 10 whereas the binary number system consists only two digits (0 and 1) which make their operation easier. The …
