  • Publication number: 20230208437
    Abstract: A digitally selectable power gate with thermometer-encoded upper bits may provide solutions for problems digital power gate-based regulators. These solutions may include the use of a fully binary power gate, either in structure or by local decoding of binary control signal to an addressable row-based power gate. This provides improved performance over a row-based code rotation, which is intended to avoid instantaneous overheating of power gate devices but may not mitigate aging effects. Another solution includes ganging a primary DLVR and one or more secondaries. The primary DLVR may include a voltage sense and active controller, which may forward its PG code to secondary instances. Therm and current sensor rotation may be performed locally at the secondaries and a current monitor data may be rolled up from all ganged DLVRs.

  • Publication number: 20230168705
    Abstract: Embodiments herein relate to a feedback loop in a digital voltage regulator for controlling an output voltage. To avoid instability at light current loads, a gain of the loop is reduced as a power gate code indicates a reduced number of branches in set of current sources are enabled. In an example implementation, the code is classified into one range of a number of ranges, and the gain is set based on the one range. The gain can decrease each time the code enters a lower range, as indicated by the code crossing a threshold or predetermined value. For example, the gain can decrease by half each time the code enters a lower range.
