Abstract

The circuit comprises two transistors (32, 33) including drains and sources (21-24) and isolated gates (34, 35) respectively having dopings suitable for setting up a threshold-voltage difference between these two transistors. The reference-voltage source thus obtained can easily be produced as an integrated circuit. The circuit is advantageously used in a battery-voltage detector device in an electronic watch. <IMAGE>
