This is a conceptual design for a super-fast waveform synthesizer. I thought up this design as a possible way to avoid the typical lock time of a PLL by doing a table lookup in real time from an analog memory table. As I thought about it some more, I came up with some other uses of the same design such as waveform compensation, waveshape conversion, attenuation, amplification, and so forth. I have attached a draft white paper along with Spice simulation results:
