  • Voltage regulators with load-dependent bias
    Patent number: 9178408
    Abstract: This document describes systems and techniques related to voltage regulators. The subject matter of this document can be embodied in a method that includes measuring an output current of a switching regulator. The switching regulator includes a high-side transistor and a low side-transistor wherein the high-side transistor and the low-side transistor are driven using a first gate voltage and a second, different gate voltage, respectively. The method also includes adjusting a direct-current (DC) voltage source of the switching regulator such that the first gate voltage is adjusted in accordance with the measured output current.
    Type: Grant
