A highly sensitive microsystem based on nanomechanical biosensors for genomics applications
(Elsevier, 2006)
Microcantilever-based biosensors are a promising tool to detect biomolecular interactions in a direct way with high accuracy. We show the development of a portable biosensor microsystem able to detect nucleic acid hybridization ...

Impact of random channel mismatch on the SNR and SFDR of time-interleaved ADCs
(Institute of Electrical and Electronics Engineers, 2004)
Using several ADCs (Analog to Digital Converters) in parallel with convenient time offsets is considered as an efficient way to push the speed limits of data acquisition systems. However, a serious drawback of this ...

Current-mode fully-programmable piece-wise-linear block for neuro-fuzzy applications
(Institute of Electrical and Electronics Engineers, 2002)
A new method to implement an arbitrary piece-wise-linear characteristic in current mode is presented. Each of the breaking points and each slope is separately controllable. As an example a block that implements an N-shaped ...
