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)
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.
Telecollaboration between medical professionals is well established for images and covering medical domains like radiology, cardiology or pathology. While images profit from functionality of the DICOM standard the exchange of non-DICOM objects like documents or reports lacks support and in particular workflow integration with existing legacy systems.… (More)
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)
The presented paper includes the design and implementation of a 65 nm CMOS low-noise amplifier (LNA) based on inductive source degeneration. The amplifier is realized with an active balun enabling a single-ended input which is an important requirement for low-cost system on chip implementations. The LNA has a tunable band-pass characteristic from 4.7 GHz up… (More)
