Abstract
In a power-on reset circuit and a method of generating a power-on reset signal tolerant of variation of an ambient temperature, the power-on reset circuit includes a first power-on reset unit, a second power-on reset unit and a logic gate. The first power-on reset unit generates a first power-on reset signal that is activated at a first level of a power supply voltage at a first temperature, and is activated at a second level of the power supply voltage at a second temperature. The second power-on reset unit generates a second power-on reset signal that is activated at the second level at the first temperature, and is activated at the first level at the second temperature. The logic gate executes a logical disjunction operation or a logical conjunction operation of the first power-on reset signal and the second power-on reset signal and generates a third power-on reset signal.
