Abstract:This article presents a color light detection system integrated in 130 nm CMOS technology. The sensors and corresponding electronics detect light in a CIE XYZ color luminosity space using on-chip integrated sensors without any additional process steps, high-resolution analog-to-digital converter, and dedicated DSP algorithm. The sensor consists of a set of laterally arranged integrated photodiodes that are partly covered by metal, where color separation between the photodiodes is achieved by lateral carrier di… Show more
“…The remote sensing satellite are equipped with high-resolution spectral camera to monitor earth round the clock. The new CMOS based sensor (Strle et al, 2015;Wong, 1997) has helped to design compact HSI camera and hence its affordability has resulted in its wider adoptability in several applications. The HSI camera captures several hundred of continuous spectral channels from a given object, which ranges from IR bands, through VR to UV ranges and hence scores comprehensive imaging output over traditional RGB data based color cameras.The spectrum obtained from an HSI camera has a profile of reflection absorption ranging from 0 to 1 for a given object with respect to various spectral band.…”

“…Many conventional sensor systems adopt excessive high-performance incremental ADCs to meet worst-case requirements [20], [21] even though their requirements on resolution and speed vary with applications or operational states. Therefore, this paper presents a triple-mode reconfigurable IADC structure to provide optimal resolution with minimal power consumption.…”
This paper proposes a triple-mode discrete-time incremental analog-to-digital converter (IADC) employing successive approximation register (SAR)-based zooming and extended counting (EC) schemes to achieve programmable trade-off capability of resolution and power consumption in various smart sensor applications. It mainly consists of an incremental delta-sigma modulator and the proposed SAR-EC sub-ADC for alternate operation of the coarse SAR conversion and EC. They can be reconfigured to operate separately depending on the application requirements. The SAR-based zooming structure allows the IADC to have better linearity and resolution, and additional activation of the EC function gives the further resolution. During this reconfigurable conversion process, pipelined reusing operation of sub-blocks reduces the silicon area and the number of cycles for target resolutions. A prototype ADC is fabricated in a 180-nm CMOS process, and its triple-mode operation of high-resolution, medium-resolution, and lowpower is experimentally verified to achieve 116.1-, 109.4-, and 73.3-dB dynamic ranges, consuming 1.60, 1.26, and 0.39 mW, respectively.
