Patent ID: 11616494

Abstract:
First and second switches are connected in series between first and second terminals. A third switch is provided between a first node between the first terminal and the first switch, and a first resistive-element. A fourth switch is provided between a second node between the first and second switches, and the reference power-source. A controller switches the first to fourth switches between conduction and non-conduction states. First, third, fifth, and seventh delay-circuits are provided between the first to fourth switches and the controller and delay first, second, third, fourth control signals for switching the first to fourth switches from a conduction state to a non-conduction state, respectively. Second, fourth, sixth, and eighth delay-circuits are provided between the first to fourth switches and the controller and delay the first, second, third, fourth control signals for switching the first to fourth switches to a non-conduction state to a conduction state, respectively.
