This paper presents a low power current-mode method for monitoring differentially derived changes in pH from ion-sensitive field-effect transistor (ISFET) sensors, by adopting the Chemical Gilbert Cell. The fabricated system, with only a few transistors, achieves differential measurements and therefore drift minimisation of continuously recorded pH signals obtained from biochemical reactions such...
This paper introduces a CMOS based system that has been designed to allow parallel comparison of fragmented DNA sequences for on-chip assembly. The compatibility of different existing PC-based algorithms for implementation in CMOS is compared and the overlap-layout-consensus approach is found to be the most suitable one. The designed system comprises a scalable processing array capable of parallel...
