Paper Abstract

The CALICO sensor is a pathfinder for the development of the future infrared high speed low noise detectors for AO. Low readout noise at high readout speed is accomplished by high gain and signal processing circuitry under each pixel. The high gain makes the detector very susceptible to instability if the system noise is too high. Lnpix3, the most promising structure, has a pixel gain of 400. In this paper we will report on test results and different measures we had to take getting the detector to work.
