WebOct 25, 2024 · The purpose of BJT is to amplify the current in it. It comprises 3 terminals namely, base, emitter, and collector, and are available in 2 configurations like NPN and PNP configuration forming junction regions during operation. These transistors are used in many applications such as switches, amplifiers, clippers, and more. WebThe BJT should be in the active region, to be operated as an amplifier. If appropriate DC voltages and currents are given through BJT by external sources, so that BJT operates in active region and superimpose the AC signals to be amplified, then this problem can be avoided. The given DC voltage and currents are so chosen that the transistor ... WebApr 2, 2024 · A BJT doesn’t have a channel, though, so we need a different name; at some point people decided on the “Early effect,” after James Early, though you will see shortly that we could also call it “effective-base-width modulation.” We usually say that the collector current of a BJT in active mode is equal to the base current multiplied by β. fitting insulation between roof rafters
