Abstract

A regenerative frequency divider comprising an in-phase mixer circuit and a phase-shifted mixer circuit. At least one switching device of the in-phase mixer circuit is of a smaller scale than a corresponding switching device of the transconductance component of the in-phase mixer circuit. In some examples, at least one switching device within an input switching stage of the regenerative frequency divider forming part of the phase-shifted mixer circuit is of a smaller scale than a respective corresponding switching device within the input switching stage forming part of the in-phase mixer circuit. In some further examples, all switching devices within the phase-shifted mixer circuit are of a small scale than respective corresponding switching devices within the in-phase mixer circuit.
