Abstract
An analog to digital converter (ADC) system that includes a first amplifier configured to amplify an analog input signal to produce an amplified direct current (DC) signal, an ADC configured to receive the amplified DC signal and convert the amplified DC signal into a digital DC signal, a digital to analog converter configured to receive the digital DC signal and convert the digital DC signal into an analog DC signal, and a second amplifier configured to receive an analog alternating current (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. The ADC is further configured to receive the amplified AC signal and produce a digital AC signal. The second amplifier has a gain greater than a gain of the first amplifier.
