Abstract
A circuit and a method generate a power-on reset signal having a leading part and a trailing part. The circuit includes a startup circuit generating the leading part of the power-on reset signal and a second circuit generating the trailing part of the power-on reset signal. The power-on reset circuit is implemented by a process which does not rely on native devices having zero threshold voltage to control a circuit generating the trailing part of the power-on reset signal.
