CMOS Active Pixel Sensor (APS) Technology

Both Caltech and Non-Caltech students will be considered

Project Title:

Project Description:

Assist in the research, development, and demonstration of CMOS Active Pixel Senosr (APS) technology. Depending on the background of the student(s), activity may include modelling of sensors, simulation of readout circuits including on-chip analog-to-digital converters, design and layout of VLSI sensor test structures, measurement of test structures, and/or demonstration of existing sensors in novel miniature camera applications. The latter requires hands on electronics engineering experience.

Background Information:

The CMOS active pixel sensor was invented at JPL a few years ago and is emerging as a competitor of CCDs for numerous applications. The CMOS APS features ultra low power operation and a high level of on-chip functionality through the integration of CMOS VLSI circuits when compared to conventional charge coupled devices (CCDs). JPL is actively pursuing the research of these sensors for future NASA interplanetary space missions. JPL is also actively engaged in the transfer of this technology to US industry including AT&T, Kodak, National Semiconductor and others for likely application in multimedia and portable electronic imaging applications.
