Abstract: A switching circuit (100, 200) for switching a voltage at an output node (120), comprises a first switch element (T1) coupled between a first supply node (110) and the output node (120), the first supply node (110) being at a first supply voltage (VDD), and a second switch element (T2) coupled between a second supply node (130) and the output node (120), the second supply node (130) being at a second supply voltage (Vss)- A switch controller (140) is arranged to, dependent on an input signal (VIN), switch the switching circuit (100, 200) between a first state, in which the first switch element (T1) is in a conducting state and the second switch element (T2) is in a non-conducting state, and a second state, in which the first switch element (T1) is in a non-conducting state and the second switch element (T2) is in a conducting state, through an intermediate state in which both the first switch element (T1) and the second switch element (T2) are in the non-conducting state.

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.
