Abstract :
The feasibility of sampling with clock phases spaced by a bin size of <10ps for a multi-channel system in a 0.18 μm CMOS technology is demonstrated. The phase spacing is limited only by uncorrelated thermal noise in the system. Redundancy is introduced in addition to interpolators and offset compensation to reduce static errors to 1.5ps.
