Toward Energy Efficient Neural Interfaces

This letter presents progress toward an energy efficient neural data acquisition transponder for brain-computer interfaces. The transponder utilizes a four-channel time-multiplexed analog front-end and an energy efficient short-range backscattering RF link to transmit digitized wireless data. In addition, a low-complexity autonomous and adaptive digital neural signal processor is proposed to minimize wireless bandwidth and overall power dissipation.

Multichannel signal processors for multielement IR FPA

Structure and circuit solutions for implementing adaptive multichannel analog and digital signal preprocessing circuits integrated with readout circuits are considered. Experimental results of investigating multichannel signal preprocessing readout circuits and IR FPA based on them are represented.
