Methods of Transistor Biasing
In the interest of simplicity and economy, it is desirable that transistor circuit should have a single source of supply—the one in the output circuit (i.e. VCC). The following are the
Transistor Biasing
The below Figure shows a bias arrangement for both npn and pnp BJTs for operation as an amplifier. Notice that in both cases the base-emitter (BE) junction is forward-biased and the base-collector
BJT Amplifiers Interview Questions & Answers
1. Explain what is an amplifier? The device that amplifies the amplitude of the input signal is called the amplifier. An amplifier may be defined as a device that increases
