Abstract
Various embodiments of the present application are directed towards an integrated circuit (IC) including a first switching device, a second switching device, an inductor, and a controller. The inductor is electrically coupled to a first source/drain region of the first switching device and a first source/drain region of the second switching device at a node. The controller is configured to alternatingly change the first and second switching devices between a first state and a second state, respectively. The first switching device is in a third state before or after the second switching device transitions between the first and second states. A subthreshold voltage is applied to a first gate of the first switching device during the third state, such that the third state is between a cutoff mode and a triode mode of the first switching device.
