Apparatuses, methods, and circuits for analog signal adjustment (or baseline loop cancellation) are disclosed. In one embodiment, an apparatus for adjusting an analog input signal includes a first mixer for combining the analog input signal and an adjustment signal; an analog signal conditioning circuit that receives an output from the first mixer and provides a conditioned analog signal; an analog-to-digital converter (ADC) that converts the conditioned analog signal to a first digital signal; a first logic block that provides a correction signal and the adjustment signal; and a second mixer that combines the first digital signal and the correction signal, and provides a digital output signal.
