Abstract

A circuit includes first to third transistors. The first transistor includes a first terminal coupled to a first voltage, and a second terminal coupled to a connection. The second transistor includes a gate terminal coupled to the gate terminal of the first transistor, a first terminal coupled to a second voltage, and a second terminal coupled to the connection. The third transistor includes a first terminal coupled to the connection, a second terminal coupled to a node between the second terminals of the first and second transistors. The third transistor is controlled to be turned ON at a beginning of a first edge of a driving signal on the connection to pull a voltage of the driving signal on the first edge toward a threshold voltage, and be turned OFF in response to and after the voltage of the driving signal on the first edge reaching the threshold voltage.
