ABSTRACT:
The invention mainly relates to a power on reset signal generating circuit and method thereof wherein said reset signal remains as a constant being independent of rising or descending power or repeated switching. The power on reset signal circuit can be implemented by a conventional RC power on reset circuit together with a coupled N-type transistor switch to charge or discharge the capacitor inside the conventional RC power on reset circuit.
