  • Publication number: 20250088182
    Abstract: Systems and methods for operating a driver circuit are described. In a first region of a transition from an input signal to an output signal, a circuit can control a slew rate of the output signal to a first rate. The first region can terminate prior to the output signal reaching a predefined threshold voltage. In a second region of the transition, the circuit can reduce the slew rate of the output signal to a second rate lower than the first rate. The output signal crosses the predefined threshold voltage in the second region. In a third region of the transition, the circuit can increase the slew rate of the output signal to a third rate greater than the second rate. The transition can complete in the third region. The circuit can output the output signal to drive a transistor in an output drive stage of the driver circuit.

  • Patent number: 7027308
    Abstract: A PCB having a card slot receiving a card provided with signal input/output pins and a circuit element to provide extended capability is inserted, and having data transmission pins, a power pin and a ground pin in correspondence to the signal input/output pins, comprises an electronic device internally provided for impedance matching with the card, and having a first end connected to one of the data transmission pins and a second end connected to one of the power pin and the ground pin. With this configuration, a card slot internally comprises an electronic device for impedance matching, so that a space of the PCB can be efficiently utilized.
