Abstract
According to an embodiment, a capacitance determination circuit is provided comprising a voltage controlled oscillator configured to generate a frequency signal whose frequency depends on a control voltage supplied to the voltage controlled oscillator, a capacitor coupled to the voltage controlled oscillator wherein the control voltage depends on a voltage across the capacitor and a processing circuit configured to generate, based on the frequency signal generated by the voltage controlled oscillator over a time interval comprising at least one phase in which the capacitor is charged and comprising at least one phase in which the capacitor is discharged, an indication of the capacitance of the capacitor.
