Abstract
An oscillator is configured to generate a signal with a frequency sweep, the oscillator having circuitry comprising a set of capacitors, each capacitor of the set of capacitors being switchably connectable in parallel in the circuitry so that the frequency of the signal has an intrinsic dependence on the number of the capacitors connected, a shift register controllable by a clock line and comprising a number of bits, each bit of the number of bits controlling connection of a respective capacitor of the set of capacitors so that the capacitors are connectable or disconnectable in a pre-determined order by shifting, respectively, activation or de-activation bits into the shift register, wherein the shifting is paced by the clock line; and a clock signal generator configured to output a clock signal with a time modulation on the clock line.
