Parameter determination in analog circuit optimization

This paper presents an approach to parameter determination in analog circuit optimization. Based on the theory on all-nonzero solutions, circuit parameters can be determined with negligible searching time by solving a system of equations which are constructed from performance functions. The proposed approach needs only specifications of minimal and maximal values of design parameters and it can find all feasible solutions. Necessary and sufficient condition for the existence of values of circuit parameters for a set of given performance functions is also presented.
