Abstract

The proposed switched capacitor converter for energy harvesting applications can have a wide input range of 0.25V to 2V.The input nonlinear adaptive voltage position (INAVP) control and feedforward compensation can decrease ΔVoutand the settling time in line transients. The mismatch calibration circuit can reduce the influence caused by the mismatch in different phase. The highest peak efficiency is 87.8%. The reduced efficiency variation is 11.6% in the case of 800% Vin perturbation.
