摘要：

A multi-path integrate-and-fire circuit is proposed as a new method of providing prosthesis sensory feedback in an effort to improve the response to dynamic stimuli. The proposed integrate and fire (I&F) utilizes adjustable thresholds and offsets on each path to provide two degrees of freedom to correctly match afferent firing frequencies. The proposed I&F was designed in TSMC 65 nm and its functionality was confirmed through simulations and comparing the response to afferent firing patterns expected for three sets of excitations.
