Various systems and methods for analog to digital conversion are disclosed. For example, some embodiments of the present invention provide analog to digital conversion systems. The analog to digital conversion systems include a first integrator and a second integrator, and a first summation element and a second summation element. An output of the first summation element is electrically coupled to the first integrator, and an output of the first integrator is electrically coupled to the second integrator. An output of the second integrator is electrically coupled to the second summation element. The analog to digital conversion systems further include an analog to digital converter that is electrically coupled to the first summation element via a digital to analog converter. An input to the analog to digital conversion system is electrically coupled to the first summation element, and the input is electrically coupled to the second summation element via a kickback filter.
