Abstract
A transmitter device includes a transmitter circuit, a voltage generator circuit, and a calibration circuit. The transmitter circuit is configured to selectively operate in a calibration mode or a normal mode in response to a first control signal, in which the transmitter circuit has a first output terminal and a second output terminal. The voltage generator circuit is configured to generate a bias voltage, in which the bias voltage has a first level in the calibration mode and has a second level in the normal mode, and the first level is different from the second level. The calibration circuit is configured to be turned on in the calibration mode according to the bias voltage and a second control signal, in order to calibrate a level of the first output terminal and a level of the second output terminal.
