Circuit and method for generating circuit power on reset signal
Disclosed is an improved circuit and method for generating a power on reset signal, the circuit being a two-stage circuit comprising a delay-stage circuit and an output-stage circuit. The delay-stage circuit delays a time for a power on reset signal generated in the output-stage circuit changing from low to high, so that a power voltage having a low rising speed may be normally reset. Further, the two stages provide charging paths and discharging paths so that the power on reset signal may be prevented from changing from high to low when it has changed from low to high, when noises are presented on the power voltage.
