More Information
Summary:A circuit includes a first power node at a first voltage level, a second power node at a second voltage level, a first voltage driver, a first current driver, and a control unit. The first voltage driver is configured to electrically couple a first output node to the first power node when a first input signal at the first input node is at a first logic state, and electrically couple a first output node to the second power node when the first input signal is at a second logic state. The first current driver is configured to inject or extract a first adjustment current into or out of a first output node. The control unit is configured to generate a measurement result of the first voltage level, and to set the first adjustment current according to the measurement result. The invention further provides a method for operating the circuit.
