Abstract :
In this paper, a high-speed current steering DAC with wave monitor circuit is proposed. Comparator-based wave monitor circuit makes it possible to detect a glitch and adjust the skew of each bit digital signal. Fabricated test chip in 40nm-CMOS demonstrates the performance improvement by glitch detection and skew adjusting. At 1GS/sec, the fabricated DAC achieved ENOB of 5.17 bit and power consumption of 2.38mW.
