Common Collector Characteristics of BJT: In the Common Collector Characteristics of BJT circuit arrangement of Fig. 4-31, the collector terminal is common to both input CB voltage and output CE…
Common Base Transistor Characteristics: To investigate the Common Base Transistor Characteristics of a diode (a two-terminal device), several levels of forward or reverse bias voltage are applied and the resulting…
Amplification in Transistor: Current Amplification in Transistor - We already know that a transistor can be used for current amplification. A small change in the base current (ΔIB) produces a large…
Transistor Voltage and Current: The Transistor Voltage polarities for an npn transistor are shown in Fig. 4-10(a). As well as conventional current direction, the direction of the arrowhead indicates the…
Transistor Operation: pnp and npn Transistor Operation - A junction transistor is simply a sandwich of one type of semiconductor material (p-type or n-type) between two layers of the opposite type.…
Full Wave Rectifier DC Power Supply: Like half-wave rectifiers, full-wave rectifiers require filter circuits to convert the output waveform to direct voltage. Figure 3-13 shows a Full Wave Rectifier DC…
Half Wave Rectifier with Capacitor Filter: Half Wave Rectifier with Capacitor Filter - When a sinusoidal alternating voltage is rectified, the resultant waveform is a series of positive (or negative)…
Zener Diodes Characteristics: When a Junction diode is reverse biased, normally only a very small reverse saturation current flows; IS on the reverse characteristic in Fig. 2-25(a). When the reverse…
