1. A data conversion circuit comprising:
a sampling capacitor; and
a controlled oscillator;
the data conversion circuit being configured to selectively charge the sampling capacitor with an input signal during a sampling phase and to discharge the sampling capacitor into the controlled oscillator so as to power the controlled oscillator in a read-out phase.
