本文提出了一种可扩展的神经记录前端，用于完全浸入式神经探针，基于两步增量Delta-Sigma ADC架构，实现了高密度、低功耗的神经信号数字化，解决了传统探针在深脑区域记录时空间分辨率低和寄生效应大的问题。
of electronics into tissue-penetrating probes improves the signal quality and reduces parasitic effects for high-density recording of in vivo neural activity. In contrast to passive neural probes or devices implementing only part of the signal chain in the probe shank [1-3], fully immersible subcortical probes allow the recording of neural signals in deep-brain regions [4]. This is achieved by directly digitizing brain activity in situ, thus avoiding a large base and allowing the probe to have a base and shank of equal width. However, this comes with a lower spatial resolution and an increased power density in the probe shank. To advance the concept of fully immersible probes, neural recording front-end architectures are required that reduce
