Neurostimulation applications require increasing versatility to tailor the treatment to the patient needs, thus improving its efficacy. In this work, we propose a fully-programmable integrated neurostimulation system capable of performing biphasic stimulation with a maximum stimuli current of ±10 mA, a maximum frequency stimulation of 50 kHz and a reduced charge mismatch of only 0.07%. Accurate electrical simulations were performed on a prototype designed with 180 nm standard CMOS process, validating the effectiveness of the proposed circuit. The obtained results are comparable with the state of the art.

Abstract
Neurostimulation applications require increasing versatility to tailor the treatment to the patient needs, thus improving its efficacy. In this work, we propose a fully-programmable integrated neurostimulation system capable of performing biphasic stimulation with a maximum stimuli current of ±10 mA, a maximum frequency stimulation of 50 kHz and a reduced charge mismatch of only 0.07%. Accurate electrical simulations were performed on a prototype designed with 180 nm standard CMOS process, validating the effectiveness of the proposed circuit. The obtained results are comparable with the state of the art.File in questo prodotto:
