Column-Parallel Single Slope ADC with Digital Correlated Multiple Sampling for Low Noise CMOS Image Sensors

This paper presents a low noise CMOS image sensor (CIS) using 10/12 bit configurable column-parallel single slope ADCs (SS-ADCs) and digital correlated multiple sampling (CMS). The sensor used is a conventional 4T active pixel with a pinned-photodiode as photon detector. The test sensor was fabricated in a 0.18 colonm CMOS image sensor process...

A Double-mode Linear Imaging System for IC-compatible Microspectrometers in Visible Light

In this thesis, a double-mode linear imaging system is designed for the application of microspectrometers. The imaging system is optimized so as to work with a Planar Double Grating System and a Linear Variable Optical Filter, the combinations of which would be suitable candidates of high-resolution low-cost microspectrometers. This linear...
