Abstract

An electronic circuit includes a first oscillator, a second oscillator and ancillary circuitry. The first oscillator is configured to generate a first clock signal and has a first wake-up delay. The second oscillator is configured to generate a second clock signal and has a second wake-up delay that is shorter than the first wake-up delay. The ancillary circuitry is configured to provide the second clock signal as an output clock signal during wake-up of the first oscillator, and, following the first wake-up delay, to provide the first clock signal as the output clock signal.
