The experimental comparison of several correlated sampling methods in linear IR FPA

Some correlated sampling techniques were introduced, auch as the correlated double sampling, quad-delta sampling and differential averager, which are effective methods to reduce KTC noise in readout circuit due to the MOSFET transistor used for resetting the voltage on capacitance. Theoretically ana lyzed was the another advantage of these methods in attenuating the input n oise including white noise and 1/f noise, then these techniques were applie d to linar infrared focal plane array (FPA). Results were analyzed and comp ared for different methods.
