摘要

We present a very low noise front-end solution for the readout of an array composed of 10 μ-bolometers. The system consists of a cold JFET and a room temperature second stage. The optimization of the second stage feedback configuration allowed to minimize the overall noise figure. A very simple current generator having a large output impedance has been developed and is used for biasing the cold JFET
