Abstract:
A transceiving circuit resistance calibrating method, which is applied to a transceiving circuit. The method includes: inputting a first current to a transmitter to generate a first output voltage, wherein the first current is generated according to a ratio between a predetermined voltage and an inner resistor of a chip; inputting a second current to a transmitter to generate a second output voltage, wherein the first current is generated according to a ratio between the predetermined voltage and a predetermined resistor; and adjusting a first adjustable resistance module according to a difference between the first output voltage and the second output voltage.
