An ultra-high speed 1:2 demultiplexer for optical fiber communication systems is designed utilizing the IHP 0.25 μm SiGe BiCMOS technology. The latch of the demultiplexer core circuit is researched. Based on the current measurement condition, a high-gain and wide-bandwidth clock buffer is designed to drive large load. Transmission line theory for ultra-high speed circuits is used to design matching network to solve the matching problem among the input, output and internal signals. The transient analysis shows that this demultiplexer can demultiplex one 100 gb/s input into two 50 gb/s outputs. The chip area of it is 0.7 mm×0.47 mm, the input and output data are both at 400 mVP-P PCML standard voltage level, and the power consumption of the IC is 900 mW at the power supply of -4 V.

Scott formulated his version of Boolean-valued models in 1967, He proved that the V（B） is a Boolean-valued model of ZFC, i. e. every axiom of ZFC has Boolean value 1, and assumed the GCH. Then, if B satisfies ccc and |B|=2No, V（B） GCH （see [1]）. In this note we construct the model △（B） on the basis of V（B）. Our main results are:（1）△（B）) is a Booleanvalued model of gb. （2） Assume the GCH. Then, if B satisfies ccc and |B|=2No, △（B） GCH. （3） The maximum and minimum principle is true in △（B）. （4） △（B）（B≠{0, 1}） is a Boolean-valued model of QM.

In this paper, the problem how to reduce the gb effect in SC filters is discussed. A new generalbiquadratic SC structure in which the gb effect is reduced is developed. The structure is stray-insensitiveand has very low W0 and Q sensitivities. Using the low-pass SC filter for an example, method of reducingthe gb effect has been shown in detail.

Laser linewidth is the important determinant of applying coherent optical orthogonal frequency division multiplexing （CO-OFDM） in optical transmission systems. The laser linewidth impairments in 100-gb/s polarization division multiplexing CO-OFDM （PDM-CO-OFDM） system without optical dispersion com- pensation are compensated by the phase drift compensator （PDC） based on Mth-power-law method located at the receiver. PDC is more effective to compensate the phase drift due to laser linewidth. Simulating results show that the maximum Q factor can be increased by almost 〉10.0 dB for bemk-to-back （BtoB）. For the 100-kHz linewidth system of 800-km system, a benefit of about 4.9 dB is possible for the maximum Q factor.
