A Self-Powered Asynchronous Image Sensor With TFS Operation

“…Photodiode stacking can also be employed to slightly increase V oc [19], but still DC-DC conversion might be necessary to power a real system [21]. [19], [20], [31], [32]. The core is composed of a classic three-stage Dickson DC-DC converter.…”

“…Fig.4(a) shows the schematic of the DC-DC converter core. The DC-DC converter steps up the V EH voltage to 700 mV, since the open-circuit voltage of a silicon photodiode is measured to be in the range of 250-450 mV at a luminance of 10-10,000 lux[19],[20],[31],[32]. The core is composed of a classic three-stage Dickson DC-DC converter.…”
