Abstract
An LC oscillator powering arrangement comprises an LC oscillator configured to provide an oscillating signal output; a current source configured to supply the LC oscillator with a supply current, the current source during operation being controlled by a control voltage and supplied with a supply voltage subject to supply voltage ripple; and a replication block configured to generate an amplified replica of the supply voltage ripple directly from the supply voltage and to overlay the replica on the control voltage.
