Circuit for generating a pulse-shaped signal.

摘要

A first transistor (PM1) arranged as a current source is 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 reset signal in bistable circuits.
