Title
(EN) POWER DISTRIBUTION NETWORK ADAPTED FOR IMAGING ARRAYS
(FR) RÉSEAU DE DISTRIBUTION D’ÉNERGIE ADAPTÉ POUR DES RÉSEAUX D’IMAGERIE
Abstract
(EN)
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.

La présente invention concerne un réseau de distribution d’énergie. La distribution d’énergie peut être appliquée à des réseaux d’imagerie et à d’autres circuits qui incluent un grand nombre de conducteurs qui doivent être pilotés de sorte que les conducteurs sont polarisés de sorte que sensiblement le même courant s’écoule dans chaque conducteur. Le réseau de distribution d’énergie inclut une pluralité de lignes de bit et un premier réseau de connexions d’énergie. Chaque ligne de bit est connectée à un emplacement différent sur un premier bus d’énergie, qui est divisé en une pluralité de premiers segments conducteurs. Chaque premier segment conducteur est connecté à une pluralité des lignes de bit. Chaque ligne de bit inclut une source de courant constant qui amène un courant de polarisation à s’écouler dans la ligne de bit et à travers le premier bus d’énergie. Le premier réseau de connexion d’énergie inclut une pluralité de trajets conducteurs qui connectent un segment correspondant des premiers segments conducteurs à un premier rail d’énergie.
