26.7 A 2.6b/cycle-architecture-based 10b 1 JGS/s 15.4mW 4×-time-interleaved SAR ADC with a multistep hardware-retirement technique
TLDR
In this paper, a multi-step hardware-retirement (MSHR) technique, which disables low-accuracy hardware blocks of scaled sizes with the requirement relaxations from redundancies in an advancement to the reconfiguration scheme in the work of Kong et al. (2013), is reported to alleviate the overhead of additional logic and DACs for ADCs, requiring high resolutions. Expand
