Abstract
An oscillator circuit comprises a first tank circuit comprising an inductive element and a capacitive element coupled in series between a first voltage rail and a first drive node. A feedback stage is coupled to a first tank output of the first tank circuit and to the first drive node. The feedback stage is arranged to generate, responsive to a first oscillating tank voltage present at the first tank output, a first oscillating drive voltage at the first drive node in-phase with a first oscillating tank current flowing in the inductive element and the capacitive element, thereby causing the oscillator to oscillate in a series resonance mode of the inductive element and the capacitive element.
