Abstract
The present disclosure discloses a direct current (DC)-DC boost converter, which includes a battery terminal providing a battery voltage, a charge pump coupled between the battery terminal and an interior node, and a power inductor coupled between the interior node and a power supply terminal that provides a power voltage to a radio frequency transceiver. The charge pump is configured to provide an interior voltage at the interior node based on the battery voltage. Herein, the interior voltage toggles between the battery voltage and two times the battery voltage. The charge pump includes a first switch coupled between the battery terminal and the interior node, a second switch coupled between the battery terminal and a connecting node, a third switch coupled between the connecting node and ground, and a flying capacitor coupled between the interior node and the connecting node of the second switch and the third switch.
