Abstract
An electronic device is provided that includes a power-on-reset (POR) circuit. The POR circuit includes a trigger stage configured to change an output if a first power supply voltage level exceeds a threshold voltage level and a first inverter and a second inverter being cross-coupled. An output of the second inverter is the POR output of the power-up reset circuit. The output is coupled to the trigger stage for switching the trigger stage off in response to a change of a signal at the output of the second inverter. The first inverter is dimensioned to follow with a voltage level at an output an initially rising slope of the first power supply voltage level and the second inverter is dimensioned to keep a voltage level at an output at a second power supply voltage level during the initially rising slope of the first power supply voltage level.
