摘要： Embodiments of a drain modulator that uses high power switch sensing to control active pulldown are generally described herein. In some embodiments, a logic and sense module is arranged to receive a control signal for controlling an on and an off state of an input of a switch to turn a high power voltage at an output of the switch on and off. A pullup module and a pulldown module are coupled to the input of the switch. An active pulldown module coupled to the output of the switch. The logic and sense module monitors the input to the switch and activates the active pulldown module to drain the output of the switch to a zero voltage when the input of the switch transitions to the off state.
