Claim 6:
7. The servo motor drive circuit according to claim 1, wherein the drive signal in each pulse period comprises a pulse valid level signal and a pulse invalid level signal in sequence; and
the first comparing unit is configured to: determine a pulse valid duration according to a preset duty ratio and the pulse period value, wherein the pulse valid duration is a product of the preset duty ratio and the pulse period value; send the pulse valid level signal to the servo motor when the timing duration is less than or equal to the pulse valid duration; and send the pulse invalid level signal to the servo motor when the timing duration is greater than the pulse valid duration.
