Micropower Electronics deals with the operation of modern electronic equipment at micropower levels and the problems associated with micropower electronics. Topics covered include the relations between minimum required power density and frequency response for semiconductor triode amplifiers; physical realization of digital logic circuits; micropower microelectronic subsystems; and metal-oxide-semiconductor field-effect devices for micropower logic circuitry. This book is comprised of 10 chapters and begins with an analysis of fundamental relationships and basic requirements pertinent to the physical realization of minimum power in electronic devices and circuits. The following chapters focus on the implementation of the criteria of micropower electronics in one way or another for the design of specific devices and circuits. A microminiature digital integrator using micropower circuits is described, along with a multiple emitter transistor in low-power logic circuits. The static and dynamic performance of micropower transistor linear amplifiers is also discussed. This monograph will be a valuable resource for scientists and designers concerned with solid-state physics or solid circuits.
