An integrated 9-channel time digitizer with 30 ps resolution

An integrated 9-channel time digitizer with 30 ps RMS resolution, 496 /spl mu/s range, and 50 mW power consumption in 0.6 /spl mu/m CMOS uses a three-stage delay line interpolation and delay-generation principle that divides the 66 MHz clock period into 512 bins using only 45 delay elements.
