Abstract
A voltage-following current mirror is shown to be a useful building block in the design of both single stage, high gain cascade amplifiers and differential to single-ended converters using n-channel depletion-mode GaAs MESFETs. After reviewing past work on such single-stage amplifiers and converters, the authors describe their combination to realize high gain, differential input, operational amplifiers. Performance results are presented
