Method and apparatus for bandpass digital-to-analog conversion
Abstract:
The disclosed embodiments provide method and apparatus for digital to analog conversion of a signal that may be limited to a bandpass frequency. In an exemplary embodiment, a bandpass DAC is disclosed which includes a plurality of gates. Each gate receives a carrier signal and one of a plurality of input bits of a digital data. A combiner network is provided which includes a plurality of lossless elements corresponding to each of the plurality of gates. The combiner network receives the gate outputs and provides a digitally weighted signal. A resonating element connected to the combiner network resonates the combiner network and provides a filtered output signal which is linearly combined.
