In this paper we present preliminary results from our research on CMOS active pixel image sensors (APS) suitable for space applications where radiation hardness, random pixel readout, low power consumption and minimum volume is of particular importance. The APS detector structure offers important advantages compared to CCD sensors that are used in most of today's scientific imagers. The design, layout and some preliminary test results from photogate and photodiode pixel structures, including in-pixel buffer amplifiers and correlated double sampling circuitry, is presented. Both single detector elements and three imaging arrays of 32 by 32 pixels have been developed and tested. The development has been carried out using standard CMOS DLP/DLM technology with 1.2 micrometer design rules.
