A CMOS imaging sensor is described that uses active pixel sensor (APS) technology which permits the integration of the detector array with on-chip timing, control and signal chain electronics. This sensor has been used to implement a CMOS APS camera-on-a-chip.
An addressable matrix of 32 CMOS transistors was designed into a test chip to be flown on the Combined Release and Radiation Effects Satellite (CRRES). In this paper the matrix is described along with a SPICE-like parameter extraction procedure called JMOSFIT, and Cobalt 60 radiation test results are presented that illustrate the shift in the 21-MOSFET parameters derived from JMOSFIT.
The technology for obtaining custom integrated circuits from CMOS-bulk silicon foundries using a universal set of layout rules is presented. The technical efforts were guided by the requirement to develop a 3 micron CMOS test chip for the Combined Release and Radiation Effects Satellite (CRRES). This chip contains both analog and digital circuits. The development employed all the elements required to obtain custom circuits from silicon foundries, including circuit design, foundry interfacing, circuit test, and circuit qualification.
