Magnetoresistive asymmetry compensation

A method comprising:

• receiving, at a digital magnetoresistive asymmetry (MRA) compensation circuit from an analog-to-digital converter (ADC), a digital sample sequence corresponding to an analog signal;
• performing digital MRA compensation on the digital sample sequence at the digital MRA compensation circuit;
• outputting an MRA-compensated sample sequence from the digital MRA compensation circuit;
• and
• producing, at a digital backend (DBE), a bit sequence corresponding to the analog signal based on the MRA-compensated sample sequence.

An apparatus comprising:

• a continuous time front end (CTFE) configured to:
• receive an original analog signal;
• generate an analog signal by adjusting a dynamic range of the original analog signal to correspond to an input range of an analog-to-digital converter (ADC);
• provide the analog signal to the ADC;
• the ADC configured to convert the analog signal to a digital sample sequence;
• a digital magnetoresistive asymmetry (MRA) compensation circuit configured to:
• receive the digital sample sequence from the ADC;
• perform digital MRA compensation on the digital sample sequence;
• and
• output an MRA-compensated sample sequence.
