Abstract
A signal compensation device is disclosed. The signal compensation device includes an operation circuit and a modulation circuit. The operation circuit is configured to generate a control signal according to a first data signal and a second data signal, in which the second data signal is generated according to the first data signal by a signal conversion circuit. The modulation circuit is configured to provide a loop gain according to the control signal to compensate an attenuation of the signal conversion circuit.
Claims12
A signal compensation device, comprising:
- an operation circuit, configured to generate a control signal according to a first data signal and a second data signal, wherein the second data signal is generated according to the first data signal by a signal conversion circuit;
- and
- a sigma-delta modulation circuit, configured to modulate the first data signal using a loop gain according to the control signal to compensate an attenuation of the signal conversion circuit;
- wherein the signal conversion circuit comprises a transmitter conversion circuit and a receiver conversion circuit, and the transmitter conversion circuit is configured to receive the first data signal and the modulated first data signal.
