Abstract
A power on reset signal generating apparatus is provided. The power on reset signal generating apparatus includes a trigger capacitor, a reference current supplying circuit, and a current regulator. One end of the trigger capacitor is coupled to a ground voltage, and the other end of the trigger capacitor generates a power on reset signal. The reference current supplying circuit is coupled to a signal generating end. The current regulator is coupled to the signal generating end, and the signal generating end draws a splitting current to adjust the value of the current received by the trigger capacitor.
