TL;DR: The guidelines to design a true random bit generator (TRBG) circuit with a predefined minimum entropy are discussed and the design strategy is based on a feedback control procedure that allows to dynamically change the system parameters for the correction of the circuit "nonidealities" (e.g., the circuit offsets).

TL;DR: A family of nonlinear congruential generators (NLCGs) based on the digitized Reacutenyi map is considered for the definition of hardware-efficient pseudorandom number generators (PRNGs), and a theoretical framework for their study is presented.

TL;DR: In this paper, the authors presented results concerning the classification of water solutions with ethanol and other volatile organic compounds by means of SnO2 sensors, in terms of selectivity and repeatability.

TL;DR: To analyze how the sensor dynamic response changes as a function of the CO concentration, the authors individuate a temperature profile, which ensures satisfactory sensitivity to the target gas and very low power consumption.

TL;DR: In this paper, a set of models able to predict the behavior of tin oxide (SnO 2 ) sensors during chemical and thermal transients is presented, which are obtained through simplification of more complex physicochemical ones, taking into account both the intrinsic behavior of the sensors, observable during the exposure to an inert gas, and the extrinsic one, responsible for the sensor response in the presence of oxidizing and reducing gases.
