Abstract

In this paper, a wide input range boost converter is proposed. In consideration of the wide input voltage range, especially at very low input voltage, to guarantee the internal control circuit (ring oscillator and PFM controller) can operate correctly, an internal adaptive supply voltage generator is designed to produce 1 V supply voltage. The boost converter is fabricated with standard 0.18 μm 5P0 CMOS process. The active area of the boost converter is nearly 0.5 mm2. Measured results show that the boost converter can cold start with 700 mV input voltage and operate with input voltage range of 0.3 V-4 V, which demonstrate the design concepts of boost converter well.
