Abstract
This document describes a solution for low-power voltage regulation. According to an aspect, there is provided an apparatus comprising: a supply voltage regulator circuit configured to regulate a power supply voltage of a circuit; a comparator circuit coupled to the power supply voltage and configured to sample the power supply voltage, to compare the sampled power supply voltage with a reference voltage and, if the sampled power supply voltage is below the reference voltage, to enable the supply voltage regulator circuit to charge the power supply voltage, wherein the comparator is switched on and off in response to a clock signal; and a clock signal generator circuit configured to generate the clock signal.
