ASICs for MEMS
I was involved in the ASICs for MEMS project, sponsored by the `Norsk Forskningsrådet' and initiated by Trond Sæther at the department of physical electronics at NTNU in Trondheim, from June 2000 to June 2002. The contribution of our group to this project can be characterized by the following title.
Neuromorphic sensory-processing devices for MEMS
`Neuromorphic' is a term coined by Carver Mead in the late eighties/early nineties. His definition for neuromorphic systems was: `systems that are based on the organizing principles of the nervous system.'
Our special attention within this field is directed towards spike processing devices these days. These are asynchronous microelectronic devices that use short voltage-pulse signals for communication and processing, just like the signals that our brain cells transmit between them. This kind of information representation bears many possibilities. It is as yet hardly understood in the nervous system and only used in experimental electronics.
Two master students realized two ideas for spike processing microchips in collaboration with me. Both resulted in publications (see below).
Publications that resulted from this project
