Summary:
We propose an efficient Spice-oriented design algorithm of amplifies for attaining both the DC maximum gains and the low power consumptions. Our optimization algorithm is based on a well-known steepest descent method combining with nonlinear programming, which is realized by equivalent RC circuits composed of ABMs (analog behavior models) of Spice. The optimum parameters are given by the equilibrium points of the transient analysis. We show our Spice-oriented optimization algorithm using the sensitivity circuits in section 2, and the interesting illustrative examples are shown in section 5.
