Abstract

In this paper a new frequency compensation method based on automatic topology modification of analog amplifier circuits is presented. Starting from an uncompensated circuit topology in closed-loop configuration, a capacitance is inserted between each pair of nodes. Subsequently, the set of inserted capacitances is reduced to a manageable size using a selection algorithm based on eigenvalue sensitivity calculation. Finally, the remaining capacitances are sized by a numerical optimization method. The presented method is demonstrated on a transimpedance amplifier design for an industrial HDTV application.
