发明名称 Method and apparatus for providing a power-on reset signal
摘要 A power-on reset circuit and method for the same may provide reset signals during power-up and/or power-down cycles, to reduce the chances of error. An error may occur, for example, due to voltage fluctuations and/or the ambient temperature of circuit components. Reducing the chances of error during a power-up cycle may include setting an output node of a circuit to a reset state when a power supply voltage reaches a first voltage level and outputting a power-on reset signal to the output node when the power supply voltage equals a second voltage level higher than the first. Reducing the chances of error during a power-down cycle may include setting the output node to a reset state when the output node reaches a third voltage level between the first and second voltage levels.
