This brief presents an adaptive equalizer for high-definition-multimedia-interface (HDMI) systems with a new adaptation scheme by comparing the energy ratio in high-frequency and low-frequency bands of the equalized signal with a self-generated energy ratio. The self-generated energy ratio tracks process, voltage, and temperature variations to overcome the problem with preset energy ratio adaptation. Fabricated in 0.5- mum SiGe BiCMOS technology, the adaptive equalizer occupies 0.25 mm2 and consumes 108 mW from 3.3-V voltage supply at 2.25-Gb/s data rate. Measurement results show that it can automatically adapt to up to 10-m HDMI cables, achieving 0.1-UI peak-to-peak jitter in equalized signals. 相似文献

We construct the Fukaya category of a closed surface equipped with an area form using only elementary (essentially combinatorial) methods. We also compute the Grothendieck group of its derived category. 相似文献

We consider the implementation of the proportional delay differentiation model with adaptive waiting time priority scheduler and we address the problem of finding the appropriate scheduler differentiation parameters that achieve this model. In this paper, we propose an algorithm that can compute an analytical solution of this problem. 相似文献

The crystal structure of the title compound, [nBu2Sn(5-Cl-2-OH-C6H3CO2)2], shows that in the monomeric species the six-coordinate Sn atom exists in a skew trapezoidal bipyramidal geometry in which the four O donor atoms, derived from two asymmetrically chelating carboxylate ligands, define the basal plane and the n-butyl substituents lie over the weaker Sn? O interactions defining a C? Sn? C angle of 147.6(2)°. An unusual feature of the structure is the presence of both intra- and inter-molecular hydrogen bonding contacts which serve to stabilize the structure. The in vitro antitumour activity of this compound against mammary and colon carcinoma cell lines is also reported. 相似文献

Loran-C skywave delay detection using ARMA algorithm 总被引:3,自引:0,他引:3
The autoregressive moving average technique (ARMA) is applied to the problem of estimating the delay of Loran-C skywaves. The performance of this technique is evaluated and compared with Fourier-based methods. The simulation results show that the ARMA algorithm yields a significantly greater estimation accuracy and that it can also operate successfully with very noisy signals 相似文献

A transistor level model that fully describes the logical behavior of a circuit in the presence of bridging faults is presented for the nMOS combinational circuits. The proposed model is suitable for the circuits having static enhancement/depletion (E/D) load. Thus, the model can be applied to circuits like pseudo nMOS and CMOS non-threshold-logic (NTL). The model employs a logic transistor function (LTF) to examine the behavior of such circuits. The LTF model developed earlier for stuck faults in nMOS circuits is extended for bridging faults. Algorithms that were developed for the stuck faults in pseudo nMOS combinational circuits can be applied to generate the test vectors for bridging faults. 相似文献

Phytochemical investigation on the whole plant of Salsola foetida resulted in the isolation of three new phenolic compounds 1, 2 , and 3 , which exhibit tyrosinase inhibition with moderate antioxidant activity. Compounds 1 – 3 inhibited tyrosinase with IC50 2.61, 1.85, and 0.40 μM , while exhibiting DPPH radical scavenging activity with IC50 383, 427 and 378 μM , respectively. The structures of 1, 2 , and 3 were determined by modern spectroscopic techniques. 相似文献
