  • Receivers for digital predistortion
    Patent number: 9735741
    Abstract: Aspects of this disclosure relate to a receiver for digital predistortion (DPD). The receiver includes an analog-to-digital converter (ADC) having a sampling rate that is lower than a signal bandwidth of an output of a circuit having an input that is predistorted by DPD. DPD can be updated based on feedback from the receiver. According to certain embodiments, the receiver can be a narrowband receiver configured to observe sub-bands of the signal bandwidth. In some other embodiments, the receiver can include a sub-Nyquist ADC.

  • Multi-input analog-to-digital converter
    Patent number: 9294118
    Abstract: 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.
