ABSTRACT:
A circuit for resetting an electronic system based on voltage fluctuations in the power supply is disclosed. The circuit comprises a diode means for generating a first voltage being offset from the supply voltage, a first inverter having its input connected to the diode and powered by a reference voltage source, a second inverter having its input connected to the same reference voltage source and powered by the power supply; and an OR- or NOR- gate having its inputs from the outputs of the first and second inverters, such that its output, when asserted, resets the electronic system.
