When transistors operate in the active region, they act as amplifiers, increasing the strength of the input signal without significant alteration. This behavior is due to the movement ofcharge carriers. Consider an npnbipolar junction transistor(BJT) biased to operate in the active region, where th...

B (Base) & C (Collector). The transistor can work in three different regions like active region, cutoff region & saturation region.Transistorsare turned off while working in the cut-off region and turned on while working in the saturation region. Transistors work as an amplifier while they ...
Fig. 4.10 shows the three basic elements of an amplifier: an active element (transistor), a resistor, and a DC power supply such as a battery. A signal to be amplified is placed at the control electrode and the amplified output is taken across the series combination of resistor and battery...
To find the base current (IB) of a transistor working as a common base amplifier, we can follow these steps:1. Identify Given Values: - Current gain (α) = 0.96 - Emitter current (IE) = 7.2 mA2. Use the Rel

A simple transistor amplifier circuit diagram and schematic which can be used as a 12 watts audio transistor amplifier.An op amp IC is used to produce the gain required.
source-follower field effect transistor or via an emitter-follower bipolar transistor. So, as a good approximation, the current gain G of current mirror amplifier 10 can be expressed as a ratio between the collector currents IC11and IC12of transistors 11 and 12, respectively. G = -IC12/IC...
