Abstract
A drive circuit includes: an input stage configured to receive a first input signal and a second input signal, and to output a first output signal and a common-mode output signal, where the first input signal and the second input signal are complementary signals; an output stage configured to receive the first output signal, and to output a second output signal; and a duty cycle adjusting subcircuit configured to determine the first output signal and the common-mode output signal or a signal obtained by inverting the common-mode output signal as a control signal, and to adjust a duty cycle of the second output signal. The drive circuit determines the common-mode output signal or the signal obtained by inverting the common-mode output signal as the control signal of the duty cycle adjusting subcircuit, and adjusts the duty cycle of the second output signal to tend to a preset value.
