Readout circuits based on multicorrelated double sampling (multi-CDS) have been successfully employed in the past with multi-element semiconductor detectors. However, the conventional multi-CDS technique can be employed when a synchronism signal is a

To take advantage of the compactness of avalanche photodiode (APD) arrays, low-noise power-efficient fast charge-sensitive preamplifier chips with differential current drivers have been developed. A 16-channel and a single-channel version are availab

Long wavelength infrared (LWIR) sensor arrays were fabricated in Pb1−xSnxSe layers grown epitaxially on Si-substrates by MBE. A CaF2 intermediate buffer layer ≈30dgA thick was employed for compatibility reasons. The photovoltaic sensors are based
