A fuzzy logic controller using stochastic logic

TL;DR: In this approach, all the operations in a fuzzy logic controller that is, the membership function generation, the inference process, and the defuzzification process are implemented using stochastic logic, producing a controller with reduced hardware complexity when compared with conventional digital implementations, while maintaining a good accuracy in the results.
Proceedings ArticleDOI

Low-voltage low-power super class-AB CMOS op-amp with rail-to-rail input/output swing

TL;DR: In this article, a low-voltage CMOS class AB OTA with rail to rail input/output swing, low supply voltage and very high slew rate is presented, based on a combination of floating gate transistors, local common-mode feedback and class AB input.
Proceedings ArticleDOI

On the Optimal Current Followers for Wide-Swing Current-Efficient Amplifiers

TL;DR: The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed, and an enhanced recycling folded cascode OTA is proposed.
Proceedings ArticleDOI

Wireless Structural Health Monitoring system based on Autoregressive models

TL;DR: The design of a wireless and low-power consumption sensor network for Structural Health Monitoring (SHM) is presented and an algorithm based on Autore Progressive and Autoregressive with exogenous inputs (AR-ARX) to detect structural damages is selected.
Journal ArticleDOI

Super-Gain-Boosted AB-AB Fully Differential Miller Op-Amp With 156dB Open-Loop Gain and 174MV/V MHZ pF/μW Figure of Merit in 130nm CMOS Technology

TL;DR: In this article, a fully differential Miller op-amp with a composite input stage using resistive local common-mode feedback and regulated cascode transistors is presented, which operates from a 1.2V supply and has a close to rail-to-rail differential output swing.
