Abstract: A non-linear impedance terminates a transmission line. The non-linear impedance may be implemented with a back-to-back connected inverter pair. The pair acts as a non-linear resistor. A process, voltage, temperature (PVT) tracking circuit may also be provided to improve PVT tracking, with resistance of transistors locked to a calibrated resistor. The replica circuit does not appear in the signal path, and does not add capacitive load.

Abstract translation: 非线性阻抗终止传输线。 非线性阻抗可以用背对背连接的逆变器对实现。 该对用作非线性电阻。 也可以提供过程，电压，温度（PVT）跟踪电路来改善PVT跟踪，晶体管的电阻锁定到校准电阻器上。 复制电路不会出现在信号路径中，不会增加电容性负载。
