Abstract
Systems, devices, computer-implemented methods, and/or computer program products that facilitate low power, wideband multitone generation. In one example, a multitone generator device can comprise a controller operatively coupled to first and second digital-to-analog converters (DACs). The controller can apply different delays of a sampling signal to the first and second DACs to facilitate sideband suppression of signals output by the first and second DACs. One aspect of such a multitone generator device is that the multitone generator device can facilitate low power, wideband multitone generation.
Claims20
A multitone generator device, comprising:
- a controller operatively coupled to a first digital-to-analog converter (DAC) and a second digital-to-analog converter, wherein the controller applies different delays of a sampling signal to the first DAC and the second DAC to facilitate sideband suppression of signals output by the first DAC and the second DAC;
- and
- a plurality of combinational circuits operatively coupled to the first DAC and the second DAC via a multiplexer that combines the signals output by the first DAC and the second DAC to facilitate suppressing image sidebands at respective output nodes of the multitone generator device.
A computer-implemented method comprising:
- operatively coupling, by a system operatively coupled to a processor, a controller to a first digital-to-analog converter (DAC) and a second digital-to-analog converters (DACs) of a multitone generator device;
- using, by the system, the controller to apply different delays of a sampling signal to the first DAC and the second DAC to facilitate sideband suppression of signals output by the first DAC and the second DAC;
- and
- using, by the system, a plurality of combinational circuits operatively coupled to the first DAC and the second DAC via a multiplexer that combines the signals output by the first DAC and the second DAC to facilitate suppressing image sidebands at respective output nodes of the multitone generator device.
A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
- operatively couple, by the processor, a controller to a first digital-to-analog converter (DAC) and a second digital-to-analog converters of a multitone generator device;
- and
- use, by the processor, the controller to apply different delays of a sampling signal to the first DAC and the second DAC to facilitate sideband suppression of signals output by the first DAC and the second DAC;
- and
- use, by the processor, a plurality of combinational circuits operatively coupled to the first DAC and the second DAC via a multiplexer that combines the signals output by the first DAC and the second DAC to facilitate suppressing image sidebands at respective output nodes of the multitone generator device.
