Abstract
A method can include, amplifying an analog input signal to generate an amplified analog signal; modulating the amplified analog signal into a digital data stream; filtering the digital data stream with a first digital filter to generate a first filtered data stream, and selectively changing a gain of the amplifier in response to the first filtered data stream. While the digital data stream is filtered with the first digital filter, the digital data stream is filtered with a second digital filter to generate a second filtered data stream. An output digital value corresponding to the analog input signal in response to the second filtered data stream. Corresponding systems and devices are also disclosed.
