  • Publication number: 20250047277
    Abstract: In a method of operating a circuit, at a beginning of a first edge of a driving signal, a first transistor is turned ON to pull, at a first changing rate, a voltage of the driving signal on the first edge from a first voltage toward a second voltage. Then, in response to the voltage of the driving signal on the first edge reaching a threshold voltage between the first voltage and the second voltage, the first transistor is turned OFF and an output circuit is caused to start a second edge of an output signal in response to the first edge of the driving signal. The second edge has a slew rate corresponding to a second changing rate of the voltage of the driving signal on the first edge from the threshold voltage toward the second voltage. The second changing rate is controlled by a passive circuit and is smaller than the first changing rate.

  • Patent number: 12191301
    Abstract: An integrated circuit includes first to second transistors and a resistive device. The first transistor is coupled between a pad and a first voltage terminal that provides a first supply voltage. The second transistor is coupled in parallel with the first transistor. A breakdown voltage of the first transistor is different from a trigger voltage of the second transistor. The resistive device is coupled between the pad and a second voltage terminal that provides a second supply voltage higher than the first supply voltage, and operates with the second supply voltage in an electrostatic discharge (ESD) event when the first and second transistors discharge a ESD current between the pad and the first voltage terminal.
