Abstract: An oscillator circuit for providing an output clock signal is described. The oscillator circuit comprising a voltage reference, a first current source, first capacitor, first capacitor switch, second current source, second capacitor, second capacitor switch, first comparator, second comparator and flip-flop. The first comparator comprises a first chopper-stabilized comparator switchable between a compare phase and a zeroing phase in dependence on the output clock signal and arranged to operate in the compare phase in a first half-phase of the output clock signal to provide a first comparator output from comparing the first capacitor voltage to the reference voltage and in the zeroing phase in the second half-phase. The second comparator comprises a second chopper-stabilized comparator switchable between a respective compare phase and a respective zeroing phase in dependence on the output clock signal and arranged to operate in its compare phase in the second half-phase to obtain a second comparator output from comparing the second capacitor voltage to the reference voltage and in its zeroing phase in the first half-phase.
