摘要： A communications device is capable of adjusting power consumed thereby and includes a receiver and a control circuit. The receiver includes an analog-to-digital converter and a decoding circuit. The analog-to-digital converter receives receive-data from another communications device, converts the receive-data into a digital signal, and provides the digital signal to the decoding circuit for decoding. Based on the digital signal, the control circuit obtains a signaling index that indicates a communications quality of the receiver. The control circuit determines an operating state of the analog-to-digital converter and the decoding circuit in accordance with the signaling index and a receiving index. When the signaling index conforms with a reference range, the control circuit reduces a reference signal so as to reduce linearity of the analog-to-digital converter in accordance with the receiving index, and reduces a decoding capability of the decoding circuit in accordance with the receiving index.

摘要： A low-leakage IO circuit is provided. The IO circuit includes an impedance path between a pad and a power supply. The impedance path bypasses a signal path of the pad and includes a switch circuit. According to a relationship between voltages of the power supply and the pad of the IO circuit, the switch circuit selectively conducts the impedance path. When the power supply provides power normally, the switch circuit conducts the impedance path to provide a pull-up resistor between the pad and the power supply. When the power supply provides no power and its voltage is lower than a voltage of the pad, the switch circuit disconnects the conducting path to effectively reduce power leakage.
