Abstract
A power distribution network is disclosed. The power distribution can be applied to imaging arrays and other circuits that include a large number of conductors that must be driven such that the conductors are biased such that substantially the same current flows in each conductor. The power distribution network includes a plurality of bit lines and a first power connection network. Each bit line is connected to a different location on a first power bus, which is divided into a plurality of first conducting segments. Each first conducting segment is connected to a plurality of the bit lines. Each bit line includes a constant current source that causes a bias current to flow in the bit line and through the first power bus. The first power connection network includes a plurality of conducting paths that connect a corresponding one of the first conducting segments to a first power rail.
