Abstract
A bias-voltage-adjustable communications apparatus including a radio frequency RF part, an analog-to-digital converter, a digital baseband communications processor, a voltage controller, and a voltage generator. The RF part is coupled to the analog-to-digital converter and the voltage controller. The voltage generator is coupled to the analog-to-digital converter and the voltage controller. The analog-to-digital converter is coupled to the digital baseband communications processor. In an adjustment mode, the RF part is configured to generate a single-ended reference signal, where the single-ended reference signal includes a first bias voltage; the voltage generator is configured to generate a second bias voltage; and the voltage controller is configured to obtain a difference between the first bias voltage and the second bias voltage, and generate a control signal based on the difference, where the control signal is configured to adjust the first bias voltage or the second bias voltage to decrease the difference.
