Pcb vias

Bacterial phytochromes (Bphs) are ancestors of the well characterized plant photoreceptors. Whereas plant phyto-chromes perform their photoisomerization exclusively via a covalently bound bilin chromophore, Bphs are variable in their chromophore selection. This is demonstrated in the cyanobacterium CalothrixPCC7601 that expresses two Bphs, CphA and CphB. CphA binds phycocyanobilin (PCB) covalently, whereas CphB, lacking the covalently binding cysteine of the plant phytochromes, carries biliver-din IXa (BV) as the chromophore....

DO NOT have vias between bypass caps and active device – Visualize the high frequency current flow !!! • Ensure Bypass caps are on same layer as active component for best results. • Route vias into the bypass caps and then into the active component. • The more vias the better. • The wider the traces the better. • The closer the bette
