Popis:	The new efficiency-improvement low-ripple charge-pump boost converter using adaptive slope generator with hysteresis voltage comparison techniques is proposed in this paper. This proposed converter can reduce output voltage ripple, because its inductor is connected to the output. This proposed converter adopts a new controlled architecture, self-adaptive slope generator with hysteresis comparison technology, to shorten the transient response. The proposed boost converter has been fabricated with TSMC 0.35- $\mu $ m CMOS 2P4M processes, and a total chip area of $1.49~{\rm mm}\times 1.49$ mm. Its maximum output current is 260 mA when the output voltage is 3.6 V. When the supply voltage is 3.3 V, the output voltage can be 3.6–5.1 V. The maximum efficiency is 90.99% and the minimum output ripple is 10.8 mV. Finally, the theoretical analysis is verified to be correct by the experimental results.
