Abstract
A log-based closed-loop Deep Brain Stimulation system detects and processes low-frequency brain field signals to optimize stimulation parameters. The fully self-contained single-chip system incorporates LNAs, a log-ADC, digital log-filters, a log-DSP with a PI-controller, current stimulators, a two-way wireless transceiver, a clock generator, and an RF energy harvester. The 2×2mm2 180nm CMOS prototype consumes 468μW for recording and processing neural signals, stimulation, and for two-way wireless communication.
