Very simple amplifier circuit using transistor 2N3904
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.. The amount of amplification in a circuit is known as gain.The gain is the ratio between the strength of the output (current, voltage, or wattage) and the strength of the input (current, voltage.
Transistor Amplifiers Circuit Basics
The process of raising the amplitude of a weak signal without change in its frequency and shape is known as 'amplification". In order to achieve this, the input circuit of the transistor remains forward biased and the output circuit always remains to reverse biased during all parts of the signal this is known as 'transistor biasing'.
