Discrete Transistor Circuitry
This chapter deals with small-signal design using discrete transistors, specifically BJTs. Many things found in standard textbooks are skated over quickly. It concentrates on audio issues, and gives information that I do not think appears anywhere else, including the distortion behavior of various configurations.
Why Use Discrete Transistor Circuitry?
Circuitry made with discrete transistors is not obsolete. It is appropriate when:
a load must be driven to higher voltages than the op-amp can sustain between the supply rails. Op-amps are mostly restricted to supply voltages of ±18 or ±20 V. Hybrid-construction amplifiers, typically packaged in TO-3 cans, will operate from rails as high as ±100 V, but they ...
