Abstract
A circuit for detecting a variation in power supply voltage includes first transistor (PM1) arranged as a current source and connected to the input (K1) of a current mirror (NM1, NM2), whose output (K2) is connected to a second transistor (PM2) arranged as a current source and to the output of the circuit. In the event of a temporary decrease in supply voltage this circuit will produce a pulse-shaped signal on its output, which signal can be employed as a trigger signal such as a reset signal in bistable circuits.
