Hi,
Just saw this story today about a new high speed ADC IC from IBM:

128GSPS at 8bits in the 2channel variant with on die tuning:
"The 64 GS/s (giga-samples per second) chips for Semtech will be manufactured at IBM's 300mm fab in East Fishkill, New York in a 32 nanometer silicon-on-insulator CMOS process and has an area of 5 mm2. This core includes a wide tuning millimeter wave synthesizer enabling the core to tune from 42 to 68 GS/s per channel with a nominal jitter value of 45 femtoseconds root mean square. The full dual-channel 2x64 GS/s ADC core generates 128 billion analog-to-digital conversions per second, with a total power consumption of 2.1 Watts."
cheers, Jamie
