Chen, Peng (author), Huang, Xiongchuan (author), Chen, Y. (author), Wu, Lianbo (author), Staszewski, R.B. (author)To characterize an on-chip programmable delay in a low-cost and high-resolution manner, a built-in self-test based on a first-order ΔΣ time-to-digital converter with self-calibration is proposed and implemented in TSMC 28-nm CMOS. The system is self-contained, and only one digital clock is needed for the measurements. A...journal article 2018

Akter, S. (author), Sehgal, R.K. (author), van der Goes, Frank (author), Makinwa, K.A.A. (author), Bult, K. (author)This paper presents a closed-loop class-AB residue amplifier for pipelined analog-to-digital converters (ADCs). It consists of a push-pull structure with a ``split-capacitor'' biasing circuit that enhances its power efficiency. The amplifier is inherently quite linear, and so incomplete settling can be used to save power while still...journal article 2018
