Abstract: Exemplary embodiments are related to a switching voltage regulator. A device may include a first transistor having a gate configured to receive a first signal and a second transistor having a gate configured to receive a second signal. The device may also include a controller configured to measure at least one of a difference between a rising edge of the first signal and an associated rising edge of the second signal and a difference between a falling edge of the first signal and an associated falling edge of the second signal. The controller may also be configured to delay one of the first signal and the second signal if the rising edge of the first signal occurs before or after the associated rising edge of the second signal or if the falling edge of the first signal occurs before or after the associated falling edge of the second signal.
