Abstract
Circuits, methods, and systems for implementing an Analog to Digital Converter (ADC) in an Integrated Circuit (IC) are provided. An IC includes an analog modulator, a digital filter coupled to the analog modulator, and a decimator coupled to the digital filter. The analog modulator includes one or more discrete integrators and a feedback path. A first discrete integrator from the one or more discrete integrators is operable to receive an analog input of the ADC. The feedback path couples an output of the analog modulator to at least one of the one or more discrete integrators. Further, the decimator is operable to produce the output of the ADC, and the IC is operable to receive an IC configuration file that specifies how the discrete integrators are connected in the analog modulator, parameters of the digital filter, and parameters of the decimator.
