Resonant virtual supply booster for synchronous logic circuits and other circuits with use of on-chip integrated magnetic inductor
First Claim
1. A circuit for providing a supply voltage to a dynamic internal power supply node of a group of other circuits, comprising:
- a first transistor and a second transistor, of different channel types, coupled in parallel to a static power supply that supplies a constant power supply voltage; and
a magnetic inductor having a first terminal connected to a common node between the first transistor and the second transistor and a second terminal connected to the dynamic internal power supply node, to supply the dynamic internal power supply node with a boosted voltage having a magnitude greater than a magnitude of the constant power supply voltage by resonating with at least one capacitance coupled to the dynamic internal power supply node.

Abstract
Circuits and methods are provided. The circuits and methods are for providing a supply voltage to a dynamic internal power supply node of a group of other circuits. A circuit includes a first transistor and a second transistor, of different channel types, coupled in parallel to a static power supply that supplies a constant power supply voltage. The circuit further includes a magnetic inductor having a first terminal connected to a common node between the first transistor and the second transistor and a second terminal connected to the dynamic internal power supply node, to supply the dynamic internal power supply node with a boosted voltage having a magnitude greater than a magnitude of the constant power supply voltage by resonating with at least one capacitance coupled to the dynamic internal power supply node.
