A DVB-C/ITU J.83-A compliant QAM (Quadrature Amplitude Modulation) demodulator suitable for digital cable TV is proposed, which can support 4~256QAM with variable bit rate up to 80Mbps. It integrates a 10-bit 40MSPS ADC, (204,188) Reed-Solomon decoder as well as a convolutional interleaver. The chip is implemented in SMIC 0.25um CMOS technology with die(More)
In the present study, the interaction between GC-rich sequence of bcl-2 gene P1 promoter (Pu39) and two ruthenium (II) polypyridyl complexes, [Ru(bpy)2(tip)]2+ (1) and [Ru(phen)2(tip)]2+ (2), was investigated by UV–Visible, fluorescence spectroscopy, circular dichroism, fluorescence resonance energy transfer melting assay and polymerase chain reaction stop(More)
This paper studies the steady-state analysis of a system of ODE-AE-CGE arising from simulation of MOS RF autonomous circuits in which the transistor plays as current generator and its current equations could adequately represent the transistor large-signal dynamic behavior. Gauss-Seidel relaxation is applied to decouple the system so that shooting method,(More)
In this paper, we present a novel cubic-polynomial evaluation algorithm. It is suitable for VLSI implementation and the computational cost is reduced to about 66% of the previously reported method. Cubic-polynomial evaluation is a commonly used method in measurement and instrumentation [1], [2]. Among the applications involving cubic-polynomial evaluation,(More)
