Abstract
A device and method for correcting the baseline wandering of transmitting signals are disclosed. The present method and device are used to correct the baseline wandering of the first output terminal and the second output terminal of a receiver as a result of induction effect of the transformer. The present device comprises a compensation current source including a first compensation output terminal and a second compensation output terminal which are respectively connected to the first output terminal and the second output terminal of the receiver. The device further includes a voltage signal generator for generating a control voltage to control the compensation current source. The voltage signal generator employs the voltage difference of the first output terminal and the second output terminal of the receiver and a reference voltage to control the control voltage. Thereby, the compensation current value of the compensation current source is supplied to the first output terminal and the second output terminal of the receiver and is used to correct the baseline wandering.
