Abstract:
A switching circuit that switches voltage at an output node includes a first switch element configured to enable supplying a first voltage from a first supply node to the output node, a second switch element configured to enable supplying a second voltage from a second supply node to the output node, and a controller. The controller switches the first and the second switch element between a first state and a second state depending on an input voltage. In the first state, the first switch element is in a conducting state and the second switch element is in a non-conducting state, and, in the second state the first switch element is in a non-conducting state and the second switch element is in a conducting state, the switching being performed through an intermediate state in which both the first and the second switch element are in the non-conducting state.
