The invention relates to an electronic device which comprises a comparator coupled to monitor a first supply voltage level at a first supply voltage node. The comparator comprises a differential input transistor stage having one input coupled to the first supply voltage node and the other input coupled to receive a reference voltage level, a first current source configured to supply a current of a first magnitude, a second current source configured to supply a current of a second magnitude, and a capacitor. The first magnitude is greater than the second magnitude and the first current source is coupled with one side to the differential input stage for supplying the differential input stage and with the other side to a first node. The second current source is coupled with one side to the first node and with the other side to a second supply voltage node having a second supply voltage level and the capacitor is coupled with one side to the first node and with the other side to the first supply voltage node.
