Document Type and Number:
Japanese Patent JP6401294
Kind Code:
B2
Abstract:
An oscillator circuit (100) comprises a first tank circuit (T1) comprising an inductive element (L) and a capacitive element (C) coupled in series between a first voltage rail (14) and a first drive node (12). A feedback stage (F) is coupled to a first tank output (13) of the first tank circuit (T1) and to the first drive node (12). The feedback stage (F) is arranged to generate, responsive to a first oscillating tank voltage present at the first tank output (13), a first oscillating drive signal at the first drive node (12) in-phase with a first oscillating tank current flowing in the inductive element (L) and the capacitive element (C), thereby causing the oscillator (100) to oscillate in a series resonance mode of the inductive element (L) and the capacitive element (C).
