Abstract

An apparatus comprising a phase locked loop circuit including: an input configured to receive an oscillating reference signal having a reference period; a current-controlled-oscillator, CCO, configured to generate an oscillating output signal based on an input signal; an error detector configured to generate one or more error signals based on a phase difference between the reference signal and one or more feedback signals wherein the feedback signals are based on the oscillating output signal; and a charge pump circuit configured to receive at least a first of the error signals, determine a voltage indicative of a duration of the first error signal during a first part of the reference period, and provide a control current to the CCO for at least a remaining part of the reference period, wherein the control current comprises at least part of the input signal to the CCO and is based on the determined voltage.
