Abstract
A device structure includes a voltage regulator circuit, which includes: a first semiconductor die including a pulse width modulation (PWM) circuit and connected to a PWM voltage output node at which a pulsed voltage output is generated; and a series connection of an inductor and a parallel connection circuit, the parallel connection circuit including a parallel connection of capacitor-switch assemblies. A first end node of the series connection is connected to the PWM voltage output node; a second end node of the series connection is connected to electrical ground; each of the capacitor-switch assemblies includes a respective series connection of a respective capacitor and a respective switch; and each switch within the capacitor-switch assemblies is located within the first semiconductor die.
