Abstract
An area efficient distributed device for integrated voltage regulators comprising at least one filler cell coupled between a pair of PADS on I/O rail of a chip and at least one additional filler cell having small size replica of said device is coupled to said I/O rails for distributing replicas of said device on the periphery of said chip. The device is coupled as small size replica on the lower portion of said second filler cell for distributing said device on the periphery of said chip and providing maximal area utilization.
Claims19
A method, comprising:
- coupling a first node of an integrated circuit to a second node of the integrated circuit with a pass transistor disposed in a first filler cell that is located within a periphery of the integrated circuit between first and second pads of the integrated circuit and disposed in an input-output block that is located within a periphery of the integrated circuit;
- and
- controlling the pass transistor to generate a regulated voltage on the second node from an input supply voltage on the first node.
A method, comprising:
- coupling a first node of an integrated circuit to a second node of the integrated circuit with a pass transistor disposed in a first filler cell and disposed in a first input-output block that is located within a periphery of the integrated circuit that also includes a first pad disposed over the first input-output block and includes a second input-output block disposed within the periphery and having substantially the same size as the first input-output block;
- and
- controlling the pass transistor to generate a regulated voltage on the second node from an input supply voltage on the first node.
A method, comprising:
- providing a current to an integrated circuit core through a pass transistor disposed in at least one input/output block of a periphery of the integrated circuit and disposed in at least one filler cell of the periphery of the integrated circuit;
- wherein a first portion of the current is provided through the input/output block and a second portion of the current is provided through the filler cell.
A method, comprising:
- providing a current to an integrated circuit core through a voltage regulator having a component disposed in at least one input/output block of a periphery of the integrated circuit and disposed in at least one filler cell of the periphery of the integrated circuit;
- wherein a first portion of the current is provided through the input/output block and a second portion of the current is provided through the filler cell.
