DIRECT-COUPLED MICROPOWER TRANSISTORIZED PREAMPLIFIER,

Abstract

A micropower four-stage, direct-coupled, lowfrequency preamplifier was designed and tested for high-stability operation over a -40 to +60 C temperature range. The unit employs unique a-c and d-c feedback circuitry and diodes to provide interstage coupling. Test results obtained with five of these units indicate the feasibility of the design concept. This report includes a description of the circuitry, theoretical design procedures, and performance data obtained with the micropower preamplifier. (Author)
