Abstract
An method and apparatus for amplifying signals from an elemental detector in a detector array (10) is disclosed. The apparatus comprises a preamplifier (26) for amplifying the output of the elemental detector. The preamplifier comprises first differential amplifier (170) and a circuit (174) for lowering the gain of the first differential amplifier. The apparatus further comprises a postamplifier (28) for amplifying the output of the preamplifier (26). The postamplifier (28) comprises a second differential amplifier (370) and a circuit (374) for lowering the gain of the second differential amplifier.
