    Abstract: Techniques are provided to tune a gate-drive control signal for a switching device. In an aspect, a device is provided that includes a dead-time generator circuit, a first dead-time tuner circuit and a second dead-time tuner circuit. The dead-time generator circuit generates a control signal for a first switching device that is coupled to a second switching device via a switching node. The first dead-time tuner circuit generates, based on the control signal and a switching signal indicative of a voltage associated with the switching node, a first modified control signal for the first switching device. The second dead-time tuner circuit generates, based on a modified version of the switching signal and a tuning process that repeatedly modifies the control signal until a first dead-time value satisfies a defined criterion, a second modified control signal for the first switching device.
