Abstract
A moving object sensing control circuit includes: a control circuit configured to determine, based on a mode signal, whether to operate in a sensing mode or a power saving mode, and control, in the power saving mode, a sensing operation in a sensing stage and a standby operation in a standby stage; an LC oscillation circuit configured to generate an oscillation signal based on an impedance value corresponding to relocation of a moving object, by performing the sensing operation or the standby operation in response to control of the control circuit; and a sensing circuit configured to obtain a period count value of the sensing oscillation signal using a reference oscillation signal and a main oscillation signal, and output an output signal having movement information of the moving object based on the period count value, by performing the sensing operation in response to the control of the control circuit.
