英文摘要	One of the major challenge in neural prosthetic device design is to ensure charge-balanced stimulation. This paper presents a new calibration technique to minimize the mismatch between anodic and cathodic current amplitudes. The proposed circuit mainly consists of a digital and an analog calibration, where a successive approximation register (SAR) logic and a comparator are used in digital calibration while a source follower is adopted in analog calibration. With a 0. 18 ??m high voltage CMOS process, the simulation shows that the maximum current mismatch is 45 nA (<0.05%). ? 2014 IEEE.; EI; 5007-5010
