Patent ID: 7236115

Claim:
A circuit for reducing the current density on a bus coupled to a plurality of circuits, the circuit comprising: a folding amplifier array for a fine channel circuit of a folding analog-to-digital converter, wherein the folding amplifier array includes: a first amplifier circuit of the plurality of circuits, wherein the first amplifier circuit is configured to provide a first output current for the bus; a first current source circuit that is arranged to provide a first local current at an output of the first amplifier circuit such that at least a portion of the first output current is prevented from being carried on the bus; a second amplifier circuit of the plurality of circuits, wherein the second amplifier circuit is configured to provide a second output current for the bus; and a second current source circuit that is configured to provide a second local current at an output of the second amplifier circuit such that at least a portion of the second output current is prevented from being carried on the bus.
