NISP will be a multi-function instrument and function selection will be made on the fly with the help of controllable optics and electronics. It will operate at 77K over a spectral range of 0.8-2.5 um. CMOS HAWAII-H2RG will be used as Focal Plane Array detector and Sidecar ASIC will be used as front-end electronics. The detector is composed of 2K X 2K pixels and 18 microns in size. The controller can be programmed to read out the H2RG Focal Plane Array(FPA) with 1,4 or 32 modes. Its low read out noise, low dark current, high quantum efficiency and low power makes it different from other detectors. A lot of astronomical objects can be studied using this instrument. The developmental aspects and status of the control electronics will be discussed in this contribution. |
