Abstract :
A technique and circuitry for real-time high-resolution sampling of a digital waveform are presented. This circuitry has been fabricated in 1.2 μm CMOS technology, and test results show a bandwidth of up to 1 Gbit/s for the digital data and a sampling resolution externally adjustable between 25 ps and 250 ps. The fabricated circuit has shown sampling stability, monotonicity, and uniformity in sampling resolution
