Op Amp Structures
Walt Kester, Walt Jung and James Bryant
This section describes op amps in terms of their structures, and Section 1-4 discusses op amp specifications. It is hard to decide which to discuss first, since discussion of specifications, to be useful, entails reference to structures, and discussion of structures likewise requires reference to the performance feature that they are intended to optimize.
Since the majority of readers will have at least some familiarity with operational amplifiers and their specifications, we shall discuss structures first, and assume that readers will have at least a first-order idea of the definitions of the various specifications. Where this assumption proves ill-founded, the reader should ...
