Abstract

This paper presents the modeling and design of a digital nonlinear control for a fully integrated resonant switchedcapacitor (ReSC) voltage converter. An analytic stability criterion is derivedbased on a harmonic balance approach together with the dual locus method. The model translates the stability requirements into actual design parameters of the converter. The model is verified by measurements of a converter that operates up to a resonance frequency of 47MHz. The presented modelling methodology can be applied to other areas, such as digital LDO, slope shaping or digitally assisted analog.
