Abstract:
Apparatus and methods for a power-on-reset (POR) circuit are provided. In an example, a (POR) circuit can include a self-bias module configured to provide a reference voltage, a feedback module configured to provide a feedback voltage, a comparison module configured to compare the feedback voltage to the reference voltage and to provide an output signal, an inverter configured to couple the output of the comparison module to an enable input of the self-bias module, and a switch module coupled to the inverter, wherein the switch module and the inverter are configured to disabled the self bias module when the feedback voltage exceeds the reference voltage.
