In an example, there is disclosed a multiple-input analog-to-digital converter configured to receive a plurality of analog inputs and to output one or more digital outputs. In one embodiment, two input analog signals are received. The two analog signals may be mixed in a combiner, which provides them to a pipeline ADC. In another embodiment, the combiner may time multiplex the two analog input signals and provide two separate outputs signals. Advantageously, the multiple-input ADC of the present Specification may be realized with a single ADC pipeline.
