ABSTRACT:
A digital waveform generator reads out simulated .DELTA..SIGMA. ADC data for a desired periodic analog waveform from a memory and converts it, using a low-resolution high speed DAC, into a synthesized analog waveform. The .DELTA..SIGMA. digital waveform generator is preferably designed to take advantage of the natural evolution of device technologies. The memory is fabricated with older technologies, which tend to be slower but have a much higher integration. The DAC is implemented in more recent technologies, which are faster but have less integration. A speed up buffer or buffers in intermediate speed intermediate integration technologies may be included to provide a bridge between the low speed memory and the low integration DAC. As the current technologies become more well developed, and thus more integrated, and new higher speed technologies take their place, the technologies for the various components will gradually change, but the architecture should remain viable and superior to the known digital generators.
