A 6-b 1Gsample/s SiGe BiCMOS A/D Converter

Very high-speed A/D converters are widely used in hard disk read channels, high-speed Ethernet transceivers and satellite receivers. For such applications a resolution of 6-b at a sampling speed of 1GS/s or higher is usually required. In literature some CMOS implementations are reported, featuring a sampling speed between 0.8 and 1.6-GS/s and power consumption between 300 and 500mW [1,2,3,4]. T...

6-Phenyl­benzo[d]naphtho­[2,3-b]thio­phene

In the title compound, C22H14S, the r.m.s. deviation from the mean plane of the four-fused-ring naphtho-thio-phene unit is 0.056 Å. The dihedral angle between the naphtho-thio-phene plane and the pendant phenyl ring is 67.24 (6)°. In the crystal, weak C-H⋯π and π-π stacking [minimum centroid-centroid separation = 3.7466 (10) Å] inter-actions are observed, which together lead to (010) sheets.

The efficient synthesis of dibenzo[d,d′]benzo[1,2-b:4,3-b′]dithiophene and cyclopenta[1,2-b:4,3-b′]bis(benzo[d]thiophen)-6-one

With 3,3'-bi[benzo[b]thiophenyl] as starting material, dibenzo[d,d']benzo[1,2-b:4,3-b']dithiophene, a [5]heterohelicene, was synthesized efficiently in 60% yield via formylation and McMurry reaction. Cyclopenta[1,2-b:4,3-b']bis(benzo[d]thiophen)-6-one, another interesting helical ketone, was also prepared in 79% yield via deprotonation and ketonization of 3,3'-bi[benzo[b]thiophenyl]. In additio...
