The Institute of Nanoelectronics of Hamburg University of Technology is focused on the development and design of integrated circuits with analog and digital functionality. This includes low-noise amplifiers for small signals, analog-digital converters for high data rates and hard-wired data processing capability. These circuits are optimized for low power consumption. In the institute, intensive simulation studies are carried out and, then, the data for processing are generated. These data are sent to an external silicon foundry where the integrated circuits are fabricated. After that, the circuits are tested and configured for special applications, mostly in the field of medical electronics. These application specific integrated circuits (ASICs) are used, e.g. for acquisition of small bioelectrical potential, such as EMG, EEG or the signals of sensors, e. g. for pressure or for chemical agents.
For invasive applications, such as implants, a wireless data interface and a wireless energy harvester are added. The size of the integrated circuits has to be as small as possible to allow applications for implants. For flexible usage, the integrated circuits are designed in such a way that they can be configured, so that a wider range of applications can be supported.
