Simplified Explanation

The abstract describes methods and systems for choosing the voltage for a substrate connection of a bypass switch in a regulator. This is done using a bulk voltage generation circuit that is connected externally to the regulator. The bulk voltage generation circuit can select the voltage for the substrate connection from either an Input/Output (I/O) supply voltage or a core supply voltage. The selection is based on the mode of operation of the regulator and the presence or order in which the I/O supply voltage and core supply voltage are available.


Original Abstract Submitted

Methods and systems for selecting voltage for a substrate connection of a bypass switch include a bulk voltage generation circuit coupled externally to the regulator. The bulk voltage generation circuit is configured to control selection of a voltage from among an Input/Output (I/O) supply voltage and a core supply voltage for a substrate connection of a bypass switch of the regulator. The bulk voltage generation circuit is configured to select the voltage for the substrate connection of the bypass switch based on a mode of operation of the regulator and at least one of a presence or an arrival sequence of the I/O supply voltage and the core supply voltage.
