—Active safety systems are based upon the accurate and fast estimation of the value of important dynamical variables such as forces, load transfer, actual tire–road friction (kinetic friction) μ k , and maximum tire–road friction available (potential friction) μ p. Measuring these parameters directly from tires offers the potential for improving(More)
Efficient system-level design is increasingly relying on hierarchical design-space exploration, as well as compositional methods, to shorten time-to-market, leverage design re-use, and achieve optimal performances. However, in analog electronic systems, circuit behaviors are so tightly dependent on their interface conditions that accurate system performance(More)

—This paper presents an ultra-wideband (UWB) low noise amplifier (LNA) consuming 2.2-mW core dc power for 6-8.5GHz wireless applications. A common-gate input stage is cascaded with a common-source second stage to perform input impedance matching and wideband stagger-tuning amplification, while the current-reuse topology minimizes the dc power dissipation.(More)
