Abstract
Various embodiments of the present invention provide systems and methods for analog to digital conversion. As an example, a circuit for converting analog signals to digital signals is disclosed. The circuit includes a variable gain amplifier circuit, an analog to digital converter circuit, and a summation circuit. The variable gain amplifier circuit is operable to apply a first gain value to an input to yield a first amplified output, and to apply a second gain value to the input to yield a second amplified output. The analog to digital converter circuit is operable to receive a derivative of the first amplified output and to provide a corresponding first digital sample, and to receive a derivative of the second amplified output and to provide a corresponding second digital sample. The summation circuit is operable to combine the first digital sample and the second digital sample.
