  • Power on reset apparatus
    Patent number: 8508264
    Abstract: A power on reset (POR) circuit is provided. For the POR circuit, a PMOS transistor is coupled to a first voltage rail at its source. A drive circuit is coupled to the drain of the PMOS transistor and is configured to output a POR signal. A voltage divider is coupled between the drain of the PMOS transistor and the second voltage rail. A switch network is provided as well, which has first and second switches. The first switch is coupled between the gate of the PMOS transistor and the voltage divider, and the second switch is coupled between the gate of the PMOS transistor and the voltage divider. A controller is also coupled to control the first and second switches, wherein the first and second switches are complementary driven.
