Abstract
The present invention discloses a Power-On-Reset (POR) circuit with zero steady-state current consumption and stable pull-up voltage. The POR circuit achieves zero steady-state current consumption during steady operation after the POR process by cutting off a power supply to a band-gap comparator circuit and a current comparator circuit after the POR process. The present invention has high reliability and stable pull-up voltage, is less susceptible to the impact of power-on rate of power supply, temperature, and process variation, has very low steady-state power consumption, and can be integrated in a SOC chip in low-power consumption applications.
