Small-Signal and Low-Power Amplifiers

  • Denton J. Dailey


Amplifiers play a central role in electronics, in general, and are certainly of great interest to most guitarists. Amplifiers can serve several purposes. Usually the main function of an amplifier is to increase the amplitude of a signal. 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 operational amplifier configurations.
