Abstract

This paper presents the design of two novel, full HD Readout Integrated Circuits (ROICs) optimized for image sensors employing colloidal Quantum Dots (cQD). Both ROICs share a common architecture while differing primarily in the pixel design: one implements a simple 3T-sense pixel and the other uses a charge-amplifier (CA) based pixel. The two ROIC selection allows optimization of the sensor performance depending on the specific characteristic of the detector material. A full description of the architecture and circuits highlights the versatility of these ROICs.
