Abstract
A device of inductance detection, which includes: a controller, a current pulse generator, and a detector. The controller generates a control signal and an enable signal to the switching regulator according to a judge signal. The switching regulator then generates an output voltage. The current pulse generator is coupled to the controller and generates a current pulse signal to the object according to the control signal. The detector is coupled to the object and the current pulse generator, and is used to detect a reflective signal responded by the object after the object receives the current pulse signal. The detector then generates a judge signal according to the reflective signal.
