CMOS analog circuit optimization via river formation dynamics

As silicon process geometry is reduced in scale with growing Electronic Design Automation (EDA) industry, the underlying circuitry on a chip has become more complex. The cost of designing such complex systems drives towards the path of employing automation in the field of analog circuit design. In this paper, a heuristic based on river formation dynamics (RFD) is presented to design analog circuits with user-defined specifications. Here search strategy of RFD scheme is employed to advance through stringent design requirements to evaluate an optimum solution for two-stage CMOS operational amplifier circuit. Experimental results show competent performance of RFD scheme in terms of quality of solution when compared with standard optimization techniques.
