We demonstrate an optical receiver front-end using a CMOS TIA with a germanium-on-silicon PD. The amplifier only occupies 0.09 mm2 with 12 mW power consumption, and achieves a 27.5 GHz 3-dB bandwidth. The integrated silicon-based receiver shows well opened eye diagrams up to 20 Gb/s.
In this paper, we present a new method for fuzzy forecasting based on two-factors second-order fuzzy-trend logical relationship groups and the probabilities of trends of fuzzy-trend logical relationships. Firstly, the proposed method fuzzifies the historical training data of the main factor and the secondary factor into fuzzy sets, respectively, to form two-factors second-order fuzzy logical relationships...
This paper presents a new method for fuzzy forecasting based on two-factors second-order fuzzy-trend logical relationship groups and the probabilities of trends of fuzzy-trend logical relationships. We also apply the proposed method to forecast the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX). The experimental results show that the proposed method outperforms the existing methods.
