New gallium-doped silicon 128 by 192 element arrays have been achieved at CEA-LETI-LIR (Infrared Laboratory) for imaging in the 8 - 14 micrometer spectral range. This program is in keeping with the previous detector development for the ISOCAM camera (32 by 32 element arrays) and for ground-based observation (64 by 64 element arrays). The main features of the new detectors are: a pitch of 75 micrometer which leads to 10 by 15 mm2 chip dimensions, two selectable storage capacitors (respectively 0.1 and 0.5 pF), a DVR readout circuit achieved in an NMOS silicon line with 1.5 micrometer design rules. The main electro- optical performances are the following: a peak responsivity of 4.0 A/W, a noise of 58 fA rms over the 0.1 - 128 Hz spectral range which is very close to the BLIP noise, and a corresponding noise equivalent power of 1.4 10-14 W.
