Imaging and Camera Technology
Tips and Tricks: Achieving the $1 mobile camera module
Reducing the cost of solid state camera modules may be incremental, like the progressive reduction in pixel dimensions and the reduction in the number of optical elements, or revolutionary, such as a switch to wafer scale packaging of imagers, production of optical components and the manufacturing of camera modules. When combined, the possible result is a solution priced at less than $1.
Ultrasound imaging system design reshaped by AFEs
Recent innovations are making it possible for new ultrasound systems to achieve much lower power and a significantly smaller footprint than ever before. Designing ultrasound systems is complex, and every feature of the analog front end (AFE) can influence system performance.
