Abstract: A manufacturing method of an electrochemical sensor comprises forming a graphene layer on a donor substrate, laminating a film of dry photoresist on the graphene layer, removing the donor substrate to obtain an intermediate structure comprising the film of dry photoresist and the graphene layer, and laminating the intermediate structure onto a final substrate with the graphene layer in electrical contact with first and second electrodes positioned on the final substrate. The film of dry photoresist is then patterned to form a microfluidic structure on the graphene layer and an additional dry photoresist layer is laminated over the structure. In one type of sensor manufactured by this process, the graphene layer acts as a channel region of a field-effect transistor, whose conductive properties vary according to characteristics of an analyte introduced into the microfluidic structure.

Abstract: Digital data signals such as, e.g., turbo-encoded data signals subject to decoding, are processed by producing a plurality of families of metrics for these signals while allowing one or more of these metrics to wrap through a respective independent wrapping operation. A decoder, e.g., a decoder for turbo-encoded digital signals computes differences of metrics selected out of the plurality of families of metrics by excluding differences of metrics derived through independent wrapping operations (e.g., wrapping metrics from different families) and generates signals representative of order relationships of combinations of corresponding unwrapped metrics as a function of said differences.

Abstract: In a multi-phase power supply voltage regulator functioning at a nominal switching frequency, one or more phases are kept off for optimizing energy efficiency at relatively low load conditions. Reactivation of stand-by phases in response to a load increase transient is made more efficiently by exploiting information already present in the output voltage control loop. The technique comprises a) deriving from the control loop information on the equivalent nominal switching frequency given by the product of the nominal switching frequency by the number of active phases; b) updating at every beat of a clock signal the instantaneous value of the equivalent switching frequency; c) determining the band of equivalent switching frequency values to which the instantaneous value belongs; d) logically combining the equivalent switching frequency information with a determined band of output current level, for switching on one or more stand-by phases in response to a load increase transient.
