Imaging detector with per pixel analog channel well isolation with decoupling

摘要

An imaging apparatus (400) includes a detector array (412) with at least one detector tile (418). The detector tile includes a photosensor array (422) with a two dimensional array of individual photosensitive detector pixels (424) located within a non-photosensitive area (426) and readout electronics (432) coupled to the photosensor array. The readout electronics includes individual analog readout channel wells (602, 604) corresponding to the individual detector pixels, wherein an analog readout channel well electrically isolates analog electrical components therein from analog electrical components in other analog readout channel wells. Decoupling circuitry optionally is located in at least one of metal layers of the individual analog readout channels or in the individual analog readout channel wells.
