24 January 2012Active pixels of transverse field detector based on a charge preamplifier
The Transverse Field Detector (TFD), a filter-less and tunable color sensitive pixel, is based on the generation of specific
electric field configurations within a depleted Silicon volume. Each field configuration determines a set of three or more
spectral responses that can be used for direct color acquisition at each pixel position. In order to avoid unpredictable
changes of the electric field configuration during the single image capture, a specific active pixel (AP) has been
designed. In this AP the dark- and photo-generated charge is not integrated directly on the junction capacitance, but, for
each color, it is integrated on the feedback capacitance of a single-transistor charge pre-amplifier. The AP further
includes a bias transistor, a reset transistor and a follower. In this work the design of such a pixel is discussed and the
experimental results obtained on a 2x2 matrix of these active pixels are analyzed in terms of spectral response, linearity,
noise, dynamic range and repeatability.
