In the case of heavy damage to retina or even eyeballs, an artificial vision system is more promising than a retinal prosthesis. Like the human retina, implementing microsaccade in the artificial vision system is necessary to avoid vision fading. In this work, an electronic-microsaccade (E-Saccade) circuit is proposed to apply convolution operation with a time-varying kernel on a still image. In addition, a synchronize logic is proposed to prevent unbalanced stimulation. Experimental results show that the proposed circuit successfully shift biphasic stimulus current in 8 directions with a frequency of up to 10 Hz. Moreover, all unbalanced stimulation is canceled by the synchronize logic, making the system intrinsically safe.
