1. A NEW EFFICIENCY-IMPROVEMENT LOW-RIPPLE
CHARGE-PUMP BOOST CONVERTER USING ADAPTIVE
SLOPE GENERATOR WITH HYSTERESIS VOLTAGE
COMPARISON TECHNIQUES
ABSTRACT:
The new efficiency-improvement low-ripple chargepump 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-μm CMOS 2P4M processes, and a total
chip area of 1.49 mm × 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.
