1. An analog to digital converter (ADC) system, comprising:

  • a first amplifier configured to amplify an analog input signal to produce an analog amplified direct current (DC) signal;

    an ADC configured to receive the analog amplified DC signal and convert the analog amplified DC signal into a digital DC signal;

    a digital to analog converter (DAC) configured to receive the digital DC signal and convert the digital DC signal into an analog DC signal; and

    a second amplifier having a gain greater than a gain of the first amplifier, the second amplifier configured to receive an analog alternating current (AC) signal, the analog AC signal comprising the analog DC signal subtracted from the analog input signal, and amplify the analog AC signal to produce an amplified AC signal;

    wherein the ADC is further configured to receive the amplified AC signal and produce a digital AC signal.
