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