Transistor as an Amplifier The transistor amplifier circuit is shown in the figure ,shows the common emitter npn amplifier circuit. VBB is connected in the input circuit in addition to the signal voltage. This d.c voltage is known as bias voltage and its magnitude is such that it always keeps the emitter-base junction forward biased … Read more

Transistor connection: Common base(CB) common Emitter(CE) common collector(CE)

by

Transistor connections There are three leads in a transistor i.e. emitter ,base and collector terminals. When a transistor is to be connected in a circuit, we requires four terminals; two for the input and two for the output. This difficulty is overcome by making one terminal of the transistor common to both input and output … Read more
