TL;DR: A very high optical bandwidth, estimated up to 120GHz, was evidenced in 10 µm long Ge photodetectors selectively grown at the end of silicon waveguides using three kinds of experimental set-ups.

TL;DR: A comparator in a low-power 65-nm complementary metal-oxide-semiconductor process (only standard transistors with threshold voltage Vt ap 0.4 V were used) is presented, where the circuit of a conventional latch-type comparator consisting of two cross-coupled inverters is modified for fast operation, even with 0.65-V supply.

TL;DR: In this paper, the authors present a theory of optical emission and absorption in silicon-on-insulator (SINR)-based integrated circuits, including the use of photodetectors.

TL;DR: In this paper, the diffusion of gold and platinum in float zone (FZ) silicon is found to be dominated by the kick-out mechanism for temperatures of 800° C and higher, whereas for temperatures below approximately 850° C the dissociative mechanism governs platinum diffusion.

TL;DR: Clocked regenerative comparators, which use positive feedback of a latch to force a fast decision, are used for many applications and are designed to extract every 4th bit of a 40Gb/s data stream.
