How do you create a npn voltage amplifier

WebObjective. In this laboratory we continue our discussion on operational amplifiers (see the previous lab here: Activity 1. Simple Op Amps) focusing on variable gain / voltage-controlled amplifiers. Most operational amplifier or op-amp circuits have a fixed level of gain. However it is often useful to be able to vary the gain. WebOct 12, 2013 · BJT (bipolar junction transistor) are widely used an amplifier, oscillator, switch etc. It is a current-driven device ( MOSFET is voltage driven), the output current is equal to the input current times a factor which is called Gain. A basic BJT has three pins: the Base, Collector, and Emitter.

Under this situation to the first order any low negative voltage(NPN-version) appearing at the emitter would set up an emitter current which would mostly flow to the collector. However a small voltage drop(~0.03V) across collector and emitter of the transistor is required to maintain a current through it.
