In this paper we present a program for the synthesis of high performance negative feedback amplifiers, called Ampdes. Ampdes requires minimal interaction from the user, and produces a design report in LaTeX format and a SPICE net list for the synthesized circuit. It has been implemented under the UNIX operating system on Sun 3 and HP workstations; a typical design session takes 30 minutes.
Ampdes searches an extremely large set of possible circuit structures (over 1.000.000), and its design stragegy is essentially technology independent, giving it an advantage over other synthesis programs. The strategy is based on methematically sound search rules instead of heuristic ones, and accurate approximations of the circuit behavior.
A refined search strategy is needed to reduce the time for a design run. This strategy is also described.
