Claim 15:
16. A memory device storing instructions that, when executed, cause a processor to perform a method comprising:
receiving an analog signal at a continuous-time front end (CTFE) circuit;
performing, via the CTFE circuit, first magnetoresistive asymmetry (MRA) compensation on the analog signal to adjust a dynamic range of the analog signal based on an input range of an analog-to-digital converter (ADC);
converting the analog signal to a digital sample sequence via the ADC;
performing, via a digital MRA compensation circuit, second MRA compensation to correct residual MRA in the digital sample sequence;
receiving, via a digital backend (DBE) circuit, an MRA-compensated digital sample sequence from the digital MRA compensation circuit; and
processing, via the DBE circuit, the MRA-compensated digital sample sequence to determine a sequence of user bits corresponding to the analog signal.
