Abstract:
A termination for a high-frequency transmission line includes a first resistor that has a first terminal coupled to a first end of a transmission line and a second terminal coupled to a first input/output pad, and a second resistor that has a first terminal coupled to the first input/output pad. The first resistor and the second resistor may provide a combined resistance that matches a nominal value of a characteristic impedance of the transmission line. The apparatus may include a third resistor having a first terminal coupled to a second end of a transmission line, and a second terminal coupled to a second input/output pad, and a fourth resistor having a first terminal coupled to the second input/output pad. The third resistor and the fourth resistor may provide a combined resistance that matches the nominal value of the characteristic impedance of the transmission line.
