A 24V Mini-Coil Magnetic Neural Stimulator with Closed-Loop Deadtime Control and ZCS Control Achieving 99.76% Charge Recovery Efficiency to a short pulse PW1 by comparing it with the comparator’s reference voltage (VREF1). PW1 is then routed to the DT controller, which outputs EN1 and the rising edge of EN2. The falling edge of EN2 is generated by the second pulse generator followed by the ZCS controller.

📄 原文摘要

of EN2 (i.e., DTEN) does not reflect the actual DT, due to the switching time of Q1-Q4 and Rice University, Houston, TX *Equally Credited Authors (ECAs) Neural stimulation has a variety of applications in neuroscience research and clinical therapies. Conventionally, stimulation is delivered by implanted electrodes, such as in intracortical microstimulation (ICMS) and deep brain stimulation (DBS). However, longterm reliability associated with the electrode-tissue interface remains a fundamental challenge [1], due to foreign body responses that can lead to glial scar formation and encapsulation of electrodes (Fig. 17.5.1). Magnetic stimulation has emerged as a promising alternative to overcome this challenge, as no direct contact is needed between the stimulation coil and tissues. Its efficacy has been clinically verified through FDAapproved transcranial magnetic stimulation (TMS) for treating neurological disorders.
