In deep submicron CMOS and BICMOS technologies, antenna effects affect floating gate charge of usual floating gate test structures, dedicated to capacitor matching measurement. In this paper a new pseudo-floating gate test structure is designed. After test structure and modeling presentation, testing method and results are given for several capacitor layouts (poly-poly and metal-metal). key wor...

Floating-point numbers and floating-point arithmetic contain some surprising pitfalls. In particular, the widely-adopted IEEE 754 standard contains a number that is “not a number,” and thus has some surprising properties. One has to be extremely careful in writing assertions about floating point numbers, to avoid these pitfalls. This column describes the problems and how a language might elimin...

Floating of bodies heavier than the supporting liquid is discussed. Floating of cylindrical, ellipsoidal bodies and rectangular plates possessing lateral dimensions smaller than the capillary length is treated. It is demonstrated that more elongated bodies of a fixed volume are better supported by capillary forces, due to the increase in the perimeter of the triple line. Thus, floating of metal...

PURPOSE We describe an unusual clinical finding of a free-floating iris cyst in a patient with recurrent iritis. METHOD The clinical finding of a free-floating iris cyst was recorded using slit-lamp photography. RESULTS A 39-year-old male with a 5-year history of recurrent right iritis was found to have a small mobile iris cyst within his right anterior chamber, first identified 3 years ago...

It is tempting to describe any structure or body part which is not in continuity with its adjacent structures as 'floating'. The indiscriminate use of this word has led to description of complex injury patterns, surgeries, congenital anomalies, functional deformities or even normal anatomical structures by a single vague term 'floating'. The article stresses the importance of proper description...
