A system and method for providing a clock-independent reset signal based on supply voltage threshold levels is described. The trip points or predefined voltage levels where the power-on-reset circuit behavior reverses (which controls the reset signal) is determined by the dimensions of the transistors selected for the voltage dividers. The system and method described allows for a clock-independent stable power-up phase while consuming a very small area of a circuit board and, in particular, on integrated circuits.
