Abstract

A prototype system to aid analog design engineers in the synthesis and analysis of CMOS analog circuits has been developed. ACAD (analog computer-aided design) differs from other tools by its extensive use of hierarchy and two-port network theory to subdivide the process of solving the small signal network functions. This allows larger circuits to be analyzed. ACAD solved and simplified all of the two-port network equations for an operational amplifier containing 29 MOS transistors, 2 resistors, and 3 capacitors by analyzing, simplifying, and combining four subcircuits. ACAD produced the correct results for the model being evaluated. These results show that computer-aided hierarchical small signal model analysis of analog circuits is possible
