  • Impedance matching driver
    Patent number: 9768774
    Abstract: A circuit may include an output circuit with an output circuit output impedance and a control circuit. The output circuit may include a driver circuit that includes an output terminal and a driver circuit output impedance at the output terminal. The output circuit may also include an adjustable impedance circuit that includes an adjustable impedance. The adjustable impedance circuit may be coupled between the output terminal of the driver circuit and a signal transmission line. The output circuit output impedance may be based on the driver circuit output impedance and the adjustable impedance. The control circuit may be coupled to the adjustable impedance circuit. The control circuit may be configured to adjust the adjustable impedance of the adjustable impedance circuit such that the output circuit output impedance approximately equals a particular impedance.
