TL;DR: This work shows the potentials of capacitive BaTiO3 /PI electrode array in the field of brain/computer interfaces and in vivo, neural experiments on the visual cortex of rats show the reliability of the capacitor.
Journal ArticleDOI
An AC-Coupled Instrumentation Amplifier Achieving 110-dB CMRR at 50 Hz With Chopped Pseudoresistors and Successive-Approximation-Based Capacitor Trimming
TL;DR: A modified chopping structure is proposed to mitigate the mismatch effect of the pseudoresistors, and a successive-approximation based capacitor trimming loop is exploited to enhance the CMRR performance primarily.
Proceedings ArticleDOI
A 40nm 1Mb 35.6 TOPS/W MLC NOR-Flash Based Computation-in-Memory Structure for Machine Learning
Yuxin Zhang,Sitao Zeng,Zhiguo Zhu,Zhaolong Qin,Chen Wang,Jingjing Li,Sanfeng Zhang,Yajuan He,Chunmeng Dou,Xin Si,Meng-Fan Chang,Qiang Li +11 more
TL;DR: A 1Mb Multi-Level (MLC) NOR Flash based CIM (MLFlash- CIM) structure with 40nm technology node was proposed to realize adaptive quantization, which comprises a current interface circuit, a multi-level analog shift amplifier (AS-Amp) and an 8-bit SAR-ADC.
Journal ArticleDOI
Sampling and Comparator Speed-Enhancement Techniques for Near-Threshold SAR ADCs
Bojun Hu,Sanfeng Zhang,Xiangxin Pan,Xiangyu Zhao,Zhaoming Ding,Xiong Zhou,Shiheng Yang,Qiang Li +7 more
TL;DR: In this paper, the sampling and comparator speed-enhancement techniques for SAR ADCs under near-threshold supply voltages are presented, where a delayed cross-coupling comparator is introduced to enhance the comparator regeneration while keeping the noise comparable.
Journal ArticleDOI
A 130-dB CMRR Instrumentation Amplifier With Common-Mode Replication
TL;DR: In this article, a commonmode replication (CM-REP) technique was proposed to improve the CMRR and input CM impedance simultaneously by eliminating the CM current flow and its mismatch effect.
