A 40V Voltage-Compliance 12.75mA Maximum-Current Multipolar Neural Stimulator Using Time-Based Charge Balancing Technique Achieving 2mV Precision

摘要

Electrical brain stimulation (EBS) is a technique to stimulate neurons by current pulses. Charge accumulation due to these pulses leads to voltage build up, causing electrode corrosion and tissue damage. To ensure the safety and longevity of EBS operation, various charge balancing (CB) methods have been introduced.
