摘要： A differential offset circuit adapted for an adaptive filter of a receiver front end is provided. The differential offset circuit includes four controllable current sources which are respectively coupled to two differential output terminals of the adaptive filter. The current magnitudes of the controllable current sources are capable of being adjusted according to design requirements so that the differential offset of the adaptive filter is mitigated to avoid that the adaptive filter outputs a distorted signal to affect the accuracy of signal transmission.

摘要： A line driver includes the following. A current replication unit replicates a reference current according to an input signal. A current mapping unit adjusts a number of P channel transistors connected in parallel and inside the current mapping unit according to control information, so as to amplify the reference current according to a magnification value. A first resistor is electrically connected between the current replication unit and a direct-current voltage. A second resistor is electrically connected to the current replication unit and the current mapping unit and generates an output signal. A signal detection unit performs integration on a part of a difference between the input signal and the output signal, thereby generating an integration signal. A magnification control unit gradually adjusts magnification information related to a reference signal, and updates the control information by the magnification information when the reference signal is equal to the integration signal.
