Abstract
An integrated circuit including a power ring and an embedded low drop-off voltage regulator is disclosed herein. The regulator is located within an inner side of the power ring. An input of the regulator is coupled to the power ring. An output of the regulator is coupled to a circuit also included in the integrated circuit. The regulator is configured to fit within a bond pad frame.
Claims18
A low drop-off regulator comprising:
- an input coupled to a power ring included in an integrated circuit;
- and
- an output coupled to an internal circuit included in the integrated circuit, wherein the low drop-off regulator is configured to modify a voltage provided at the power ring in accordance with an operating power requirement of the internal circuit, and the low drop-off regulator is included in the integrated circuit and within an inner side of the power ring.
A integrated circuit comprising:
