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.
