    Abstract: A circuit may include a first sample node configured to provide a low precision sample of an input signal, a second sample node configured to store a high precision sample of an input signal, and a first switch circuit coupled between an input and the first sample node. The circuit may further include a second switch circuit coupled between the first sample node and the second sample node and configured to limit leakage current that could discharge the second sample node.

    Abstract: A self clocking comparator for clocking a charge pump providing a high voltage output including multiple gain stages and a reset circuit. The gain stages are configured to assert the compare voltage at a first voltage level in a default state when the sense voltage is greater than the reference voltage, and to assert the compare voltage to a second voltage level in a reset state when the sense voltage falls below the reference voltage. The reset circuit resets, or otherwise forces, the gain stages back to the default state in response to the compare voltage transitioning to the second voltage level. The compare voltage oscillates while the sense voltage is less than the reference voltage at a frequency based on a magnitude of a difference between the sense voltage and the reference voltage up to a predetermined maximum frequency level.

    Abstract: An integrated circuit includes: a voltage converter to receive a first supply voltage signal via a first power path and to output a first output voltage signal; and a voltage regulator to receive the first output voltage signal and to output a regulated voltage signal. The voltage regulator may further be configured to receive the first supply voltage signal via a second power path, and to selectively output the regulated voltage signal from one of the first supply voltage signal and the first output voltage signal.
