Two integrated color detectors are presented as a solution for low cost color sensing applications. The color detection is based on lateral carrier diffusion and wavelength-dependent absorption-depth. The proposed detectors are implemented in a standard 130 nm CMOS technology without process modification or color filters. Three independent output signals… (More)
This paper decribes an approach for extending tele-collaboration to the patient and allowing the patient's participation by accessing and providing data and thereby keeping the responsibilty for maintaining a personal health record with the patient. The approach has been implemented and is in use with the nationwide tele-collaboration network TKmed.
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… (More)
In this paper an optoelectronic receiver IC for optical data storage applications is presented. The IC was developed in a 0.5¿m BiCMOS technology with integrated PIN-photodiodes. It includes a new architecture of high-speed and low-noise transimpedance amplifiers with a gain range of 130 ¿ to 270 k¿ programmable with a serial interface. The bandwidth is 260… (More)
