The search for high speed, high bandwidth A/D converters is ongoing, and techniques to push the envelope are constantly being developed. In this paper an open loop, scalable, time-interleaved ADC architecture is presented, as well as a 60 GHz Colpitts oscillator. With the use of double-sampling, the timing skew requirements between channels is greatly relaxed, allowing sampling rates of up to 40 Gs/s...
CMOS evolution by lateral lithographic shrinkage has encountered an impediment in that wires do not scale well. As a result, it would appear that the clock race is over and the future of computing lies in multicore or parallel processing. In a prior paper we have explored the implications of Amdahl's figure of merit (FOM), which suggests that for algorithms to successfully demonstrate large throughput...
Forty years ago Gene Amdahl published a figure of merit for parallel computation, which proved extremely controversial. The controversy still rages today, although those that have looked closely at this figure of merit conclude that it is correct, but perhaps misinterpreted. In this paper we will look at a small variation on that law that suggests computer designers should take a closer look at two...
