Abstract :
In this letter, a novel technique that enables the simulation of digital frequency dividers at low computation cost using conventional harmonic-balance software is presented. It relies on a continuation method, implemented with standard library elements, which is externally coupled to the core of the harmonic-balance algorithm. The technique provides a straightforward method for tracing solution curves and input sensitivity curves of frequency dividers. A digital divide-by-two monolithic microwave integrated circuit (MMIC) has been analyzed using the proposed technique.
