Classification: CPC H | IPC H

Claim 9:
10. An impedance adjustment method, adapted for a signal transmitter where the signal transmitter has a plurality of first transistors, a driving circuit and a plurality of second transistors, the impedance adjustment method comprising:
disposing the plurality of first transistors on a path for receiving a power voltage by the driving circuit;
disposing the plurality of second transistors on a path for receiving a reference ground voltage by the driving circuit;
selectively providing a bias voltage to each of gate terminals of the first transistors and the second transistors to control the corresponding first transistor and second transistor to operate in a triode region; and
selectively providing a predetermined voltage to each of the gate terminals of the first transistors and the second transistors to control the corresponding first transistor and second transistor to behave as a switch.
