Abstract
A device for generating first clock signals includes first circuits, each including a ring oscillator delivering one of the first clock signals and being connected to a first node configured to receive a first current. A circuit selects one the first clock signals, and a phase-locked loop delivers a second signal which is a function of a difference between a frequency of the first selected clock signal and a set point frequency. Each first circuit supplies the first node with a compensation current determined by the second signal, when this first circuit delivers the selected clock signal and operates in controlled mode.
