Gain for this configuration will be very low Transistor as an Amplifier. Transistor is a semiconductor device with three terminals viz., Emitter (E), Base (B) and Collector (C) and thus has two junctions viz., Base-Emitter (BE) junction and Base-Collector (BC) junction as shown by Figure 1a. Such a device can operate in three different regions viz., cutoff, active and saturation Definition: An amplifier is an electronic circuit that uses a small input signal to control a larger output signal. In electronics, amplifiers have been used since the early twentieth century. Amplification can be accomplished using vacuum tubes or semiconductor devices such as transistors or integrated circuits
. Here we just added a variable signal (V S) at the output and we are taking output as V C. The capacitors at both sides (input and output) do not allow direct current to flow towards mic and speaker side. But they will allow any variable current to flow towards the other side. Now recall the following concept. Fig-3: Addition of Signals. If we add any. Transistor as an Amplifier Transistors are the semiconductor devices used for switching or amplifying electrical signals. They are highly durable, smaller in size and operates on a low voltage supply. A Transistor is a three terminal device All types of transistor amplifiers operate using AC signal inputs which alternate between a positive value and a negative value so some way of presetting the amplifier circuit to operate between these two maximum or peak values is required. This is achieved using a process known as Biasing. Biasing is very important in amplifier design as it establishes the correct operating point of the transistor amplifier ready to receive signals, thereby reducing any distortion to the.
Because an amplifier must have two input and two output terminals, a transistor used as an amplifier must have one of its three terminals common to both input and output as shown in Fig 3.6.1. The choice of which terminal is used as the common connection has a marked effect on the performance of the amplifier When a transistor works in an active region the transistor acts as an Amplifier and when it works as a Switch it works in Cutoff and Saturation Regions. The transistor in a Cutoff State both collector base and the Emitter base junctions are reverse biased.
