The age reliability of the RF performance of CMOS radio chips must be validated prior to high volume manufacturing. In this paper, we show the results of age simulations on some RF subblock designs used in our 802.11 a/b/g radio chip transceiver for our WLAN card. Transistor age models, based on HCI and NBTI age degradation mechanisms, were derived from(More)
Malignant pleural mesothelioma (MPM) is a rare cancer originated from pleural mesothelial cells. MPM has been associated with long-term exposure to asbestos. The prognosis of MPM is poor due to the difficulty of making diagnosis in the early stage, the rapid progression, the high invasiveness and the lack of effective treatment. Although the incidence of(More)
To obtain the group properties of fuzzy quantities, Mareš introduced an equivalence relation between fuzzy quantities. However, the Mareš’s method used to prove his main theorems demands to limit the investigation to fuzzy quantities with finite support. In this paper, we discuss the properties of symmetric fuzzy numbers, show an equivalent characterization(More)
In this paper, the methodology of the reliability modeling and simulation for the state-of-the-art technology is presented. The extraction for HCI (Hot Carrier Injection) and NBTI (Negative Bias Temperature Instability) for both lifetime and aged model parameter method is discussed. The integration of these models into the transistor level and gate level(More)
