Paper Abstract

A new chip organization for CCD multiplexers to increase the cell capacity is discussed. The chip uses the interlaced readout scheme, the MCCD and the storage/transfer common electrode configuration. These three techniques triple the conventional cell capacity. The CCD multiplexer is source-coupled with a 64 x 64 element HgCdTe photovoltaic array for 3-5 μm spectral region. The cell size of the CCD is 100 x 50 μm. The detector element pitch is 50 μm. The multiplexer has the charge handling capability of 1.1 x 107 electrons/cell. A 50 dB dynamic range is obtained for all 64 x 64 elements with 8% offset variation against 300 K background radiation and 14% responsivity variation. The mean detectivity D*λρ is 1.8 x 1011 cmHz1/2/W at peak wavelength of 4.7 μm. This IRCCD realizes wide dynamic range without sacrificing detectivity.
