Low power, low noise preamplifier with offset voltage cancellation

Image Number 2 for United States Patent #5304950.

Apparatus and methods are disclosed for providing a low power, low noise preamplifier, especially useful with a Forward Looking Infrared (FLIR) sensor array. Utilizing a differential amplifier, where one half of the differential pair is shared among a plurality of channels, the power consumption of the amplifier is effectively reduced. Such an arrangement also eliminates the need for bulky coupling capacitors used in ac-coupled, single ended amplifiers. In addition, cross-talk between sensor outputs caused by detector ground impedance is reduced.
