Harmonic time domain interleave to extend arbitrary waveform generator bandwidth and sample rate

摘要

A harmonic time interleave (HTI) system, including a reference signal, a first summing component to produce a summed reference signal, a de-interleave block to receive an input signal and output a plurality of de-interleaved input signals, a plurality of digital-to-analog converters, each digital-to-analog converter configured to receive a corresponding one of a plurality of de-interleaved input signals and to output a corresponding analog signal, a plurality of mixing components, each mixing component configured to receive the summed reference signal and an analog signal from a corresponding of the plurality of digital-to-analog converters, and to output a corresponding mixed signal, and a second summing component configured to receive the mixed signal from each of the corresponding mixing components and to produce a substantially full-bandwidth analog signal representation of the input signal.

1. A harmonic time interleave (HTI) system, comprising:
a sample clock configured to provide a reference signal; a first summing component configured to receive the reference signal at a first input, to receive a second signal at a second input, and to produce a summed reference signal; a de-interleave block configured to receive an input signal and output a plurality of de-interleaved input signals; a plurality of digital-to-analog converters, each digital-to-analog converter configured to receive a corresponding one of a plurality of de-interleaved input signals and to output a corresponding analog signal; a plurality of mixing components, each mixing component configured to receive the summed reference signal and an analog signal from a corresponding one of the plurality of digital-to-analog converters, and to output a corresponding mixed signal; and a second summing component configured to receive the mixed signal from each of the corresponding mixing components and to produce a substantially full-bandwidth analog signal representation of the input signal.
