A signal amplifier circuit may include a bias circuit unit generating a first bias voltage, a level shifting circuit unit shifting a level of an input alternating current (AC) signal by an amount equal to a predetermined direct current (DC) shifting voltage so as to provide a first signal, ...
This amplifier produces about double voltage and current gain than the first amplifier circuit with almost half bandwidth in 1-4mV input-signal-range at 1 KHz frequency. Both the amplifier circuits include two additional biasing resistances. Variations in voltage gain as a function of frequency and...

A small-signal amplifier configuration such as a common emitter amplifier may step into nonlinearity if the small-signal voltage input into the circuit is not of a small amplitude. Why is the indicated phenomenon possible? How does one deal with the problem through design details? Is having an...
Other functions of an amplifier might be to buffer or isolate one device or section of a circuit from another, or perhaps to provide phase inversion. In this chapter we will examine some common small-signal amplifier circuits using bipolar and field effect transistors (FETs), as well as basic...
