First Claim
Patent Images
1. A power supply distribution system for a data converter, comprising:
- a power supply pad to receive power;
a power bus coupled to the power supply pad;
a multi-tiered tree structure set of power distribution lines coupled to the power bus to provide supply and bias power distribution in the data converter, wherein the tree structure includes at least a top tier set of power distribution trunks each supplying power to different bottom tier set of power connections; and
an array of current sources having at least a row or a column powered by the bottom tier set of power connections.

11. A method for distributing power supply in a data converter, comprising:
-
fabricating a power bus coupled to a power supply pad to receive power; fabricating a multi-tiered tree structure set of power distribution lines and connecting a top tier to the power bus in the data converter; distributing power from the power us through a top tier set of power distribution trunks each supplying power to different bottom tier set of power connections; and powering an array of current sources having at least a row or a column powered by the bottom tier set of power connections. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
