Abstract
A direct current-direct current (DC-DC) converter includes an upper transistor, a lower transistor, a first bias circuit and a second bias circuit. A first input end of the first bias circuit is coupled to a first voltage reference, a second input end of the first bias circuit is coupled to a power source (PVDD), and an output end of the first bias circuit is coupled to a gate of the upper transistor to provide a first bias voltage for the gate of the upper transistor. A first input end of the second bias circuit is coupled to a second voltage reference, a second input end of the second bias circuit is coupled to a power ground (PGND), and an output end of the second bias circuit is coupled to a gate of the lower transistor to provide a second bias voltage for the gate of the lower transistor.
