Asynchronous asymmetry compensation

A circuit configured to generate a compensated data signal, the circuit comprising:

• an input node configured to receive a data signal;
• an offset coefficient feedback loop configured to calculate an offset coefficient based on the data signal;
• a scaling unit configured to scale the offset coefficient by a first predetermined value, the scaled offset coefficient representing an estimate of an asymmetry coefficient;
• and
• an output node that outputs a compensated data signal as a function of the offset coefficient, the estimated asymmetry coefficient and the data signal.

A non-transitory computer readable medium storing instructions for causing a controller to execute the following steps:

• in a first mode:
• calculating an offset coefficient based on a data signal;
• scaling the offset coefficient to calculate an estimated asymmetry coefficient,
• generating the compensated data signal as a function of the offset coefficient, the estimated asymmetry coefficient and the data signal.
