In both of these international events, we have initiated special sessions regarding low-power imager arrays and low-power memory arrays. The growing field of "smart sensors" triggered our attention to the fact that it has been a while since such a special Issue was provided on this subject, especially with emphasis on low power. The incentive was the recent results, showing that advanced concepts utilized in one niche implemented for large arrays, can be actually beneficial for the other. Moreover, there are systems on-chip where both kind of arrays are implemented, and leverage can be sought. This gives analog and digital designers another boost for developing creative circuit solutions for low-power array based systems. Also, technology and engineering progress have enabled Active Pixel Sensors (APS) in CMOS to compete with Charge Coupled Devices (CCDs) in imaging quality and to surpass them in focal-plane image processing applications, especially for low-power systems such as the cellphone. All these developments seem to show that the field of low-power sensor and memory arrays will be exciting and growing in the future. The papers in this Special Issue cover a broad range of topics, such as smart sensory arrays, new concepts for memory design, and integrated systems. The papers also come from four different continents. We have gathered the Special Issue papers in three groups. The first is image sensor array papers, the second is newmemory array design papers, and the last is other integrated arrays.

However, this works well if illumination levels are suited to one of the two integration times. If the illumination ranges somewhere between, ...

The double in-pixel storage enables global shutter operation in addition to frame difference and WDR functions. The pixel pitch is 7 μm with a fill factor of 15%.

These sensors utilize a light source to illuminate an imager chip. The edges of the light blob, its diameter and location are parameters of interest to characterize pressure dynamics. CMOS technology allows the capture and processing of an image on a

Design of CMOS imagers, utilizing self-powered sensors (SPS) is a new approach for ultra low-power CMOS active pixel sensors (APS) implementations. The SPS architecture allows generation of electric power by employing a light sensitive device, located on the same silicon die with an APS and thus reduces power
