1. A system comprising:
signal generation circuitry operable to generate an oscillating signal, wherein
the signal generation circuitry comprises time-tracking circuitry and phase generation circuitry, wherein:
the phase generation circuitry is operable to maintain phase continuity during a frequency change, and
a phase of the oscillating signal is determined according to time elapsed since a reference time, as determined by the time-tracking circuitry.
