First dutch blind patient can see again

Posted on 26/06/2013 by | Leave a comment

Today, the dutch newspaper Trouw published an article in which it reports about the first blind dutch patient being able to see again. This is made possible by a retinal implant developed by the company Second Sight, which saw its implant called Argus II being approved by the FDA this spring. As with most types of implants, it is only able to restore the original functioning of the biological senses with a limited resolution, urging a further improvement of the implant. Nonetheless, this is a huge step forward in improving the quality of life of people suffering from a reduced or even complete failure of their biological senses.

Biomedical Electronics Lab

Dear Reader,

The Biomedical Electronics Group underwent a small name change. From now onwards, the group is called “The Biomedical Electronics Laboratory”.

Its mission is “to provide the technology for the successful monitoring, diagnosis and treatment of cortical, neural, cardiac and muscular disorders by means of electroceuticals.”

To this end it conducts research on, provides education in and helps creating new businesses in neuroprosthetics, biosignal conditioning / detection, transcutaneous wireless communication, power management, energy harvesting and bioinspired circuits and systems.

New Book: EMI-Resilient Amplifier Circuits

Posted on 13/06/2013 by | Leave a comment
EMI-Resilient Amplifier Circuits

EMI-Resilient Amplifier Circuits

van der Horst, Marcel J., Serdijn, Wouter A., Linnenbank, André C.

2013, XIV, 300 p. 75 illus., 1 illus. in color.

ABOUT THIS BOOK
Describes design methods that incorporate electromagnetic interference (EMI) in the design of application specific negative-feedback amplifiers
Provides designers with a structured methodology to avoid the use of trial and error in meeting signal-to-error ratio (SER) requirements
Equips designers to increase EMI immunity of the amplifier itself, thus avoiding filtering at the input, reducing the number of components and avoiding detrimental effects on noise and stability
This book enables circuit designers to reduce the errors introduced by the fundamental limitations and electromagnetic interference (EMI) in negative-feedback amplifiers. The authors describe a systematic design approach for application specific negative-feedback amplifiers, with specified signal-to-error ratio (SER). This approach enables designers to calculate noise, bandwidth, EMI, and the required bias parameters of the transistors used in application specific amplifiers in order to meet the SER requirements.
