Current-Mode CMOS Image Sensor

This thesis presents a current-mode CMOS image sensor using lateral bipolar phototransistors (LPTs). The objective of this design is to improve the photosensitivity of the image sensor, and to provide photocurrent amplification at the circuit level. Lateral bipolar phototransistors can be implemented using a standard CMOS technology with no process modification. Under illumination, photogenerat...

Ultra Low Power Imaging Systems Using Cmos Image Sensor Technology

The need for miniaturization in advanced science sensor systems has led to technology, the active pixel image sensor (APS). The development of CMOS timing and control electronics, imaging detector arrays, signal chains and the development of a ncw image sensor APS technology allows the integration of analog-to-digital conversion on a single integrated circuit. The impact on the-im;ging system i...

CMOS Image Sensor Featuring Current-Mode Focal-Plane Image Compression

The main feature of CMOS image sensors is that they allow for the introduction of processing hardware at the pixel level. Using this characteristic, it is possible to extract from the image only the desired data, thereby reducing the output data rate. The analog processing also has the advantage of enabling high-speed operation. Owing to these features, in the last few years there has been a st...

Neural Monitoring With CMOS Image Sensors

Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...
