Systematic synthesis method for analogue circuits. Part III. All-transistor circuit synthesis

This paper and its companion papers (subtitles Part I and Part II) together present a systematic synthesis method for analogue circuits. This paper illustrates the synthesis method by deriving and analysing some known all-transistor circuits from their specification matrices. Alternative circuits with better performance are obtained by introducing ors which are equivalent to open- and short-circuits into the initial circuit. Nullors are replaced by simple equivalent circuits of transistors and nonideal performance is evaluated. The synthesis method is shown to be a powerful tool which should be capable of generating all-transistor circuit solutions from given performance specifications.
