Imaging detector with per pixel analog channel well isolation with decoupling

An imaging apparatus, comprising:

• a detector array with at least one detector tile, the detector tile, comprising:
• a photosensor array with a two dimensional array of individual photosensitive detector pixels located within a non-photosensitive area;
• and
• readout electronics coupled to the photosensor array, the readout electronics comprising:
• individual analog readout channel wells 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;
• a plurality of metal layers;
• and
• decoupling capacitors for analog and digital circuitry of at least one detector pixel, wherein the decoupling capacitors are located in the plurality of layers between the detector pixel and the analog readout channel well corresponding to the detector pixel.
