A 450mV timing-margin-free waveform sorter based on body swapping error correction
Seongjong Kim, Joao Pedro Cerqueira, Mingoo Seok · 2016
We propose an error detection and correction technique based on local body swapping for eliminating the worst-case margin in near/sub-VTHnon-instruction parallel architectures. We apply the proposed technique on an unsupervised waveform sorter for brain computer interface microsystems, improving energy-efficiency by 49.3% and throughput by 35.6% over the baseline that is margined for the worst-case variation. The area overhead is 4.1%.
