IDEAS develops integrated circuits for space based instruments and applications. The following field are covered
Radiation Monitoring Instruments in Space
The natural radiation in space threatens satellites, materials, and astronauts. The radiation environment depends on mission trajectories and varies with solar activities. Space missions need instruments for radiation alert and forecast to protect sensitive parts and to achieve the mission goals. The radiation monitoring instruments must be small, light-weight and low power. IDEAS has designed integrated circuits for space radiation monitors that meet the requirements in terms of performance and budgets. The integration of functions on one monolithic die enables to further reduce the size and weight and cost. Integrated circuits from IDEAS make small and low power space radiation monitors.

Space Based Instruments for Fundamental Physics
Fundamental physics in space aims at understanding the formation of the universe. The study of matter and antimatter in cosmic rays, gamma-ray bursts, evidence for dark matter and dark energy. The instrumentation requirements depend on mission details, and they often mandate radiation tolerance, low power, and extreme temperatures. Integrated circuits from IDEAS are flying in low Earth orbit on the International Space Stations (ISS), in Moon orbit (CHANDRAYAAN mission), in Sun orbit (STEREO mission), on various x-ray and gamma ray missions (AGILE, ASTRO-H, FOXSI), and interplanetary missions to Jupiter (JUICE) and Mercury (BeppiColombo). IDEAS ASICs help to discover and understand the formation of the universe.

Space Based Imaging for Science and Earth Observation
Future science and Earth observation missions will use large array image sensors to acquire high resolution images with a large field of view. The applications in space require high spectral sensitivity, very low noise and special environmental durability. While science missions record a low photon flux at long exposure time and relatively slow readout speed, the Earth observation requires shorter exposure time and higher readout speed. The imaging sensors can be of various types, for example, charge coupled devices (CCD), depleted field effect transitors (DEPFET), and monolithic or hybrid CMOS image sensors. All types need auxiliary electronics that provides regulated power, analogue and digital controls, and digitization of the image data. IDEAS has developed an integrated circuit that interfaces to hybrid image sensors. This circuit combines the functions needed for the image sensor, that is, regulated power, analog and digital control, and high-speed digitization of the image data. IDEAS ASICs for large array image sensors support the next generation of hybrid image sensors for Science and Earth observations.
