Abstract:
1. A method for generating one or more waveforms, comprising: generating a first toggle signal at a first signal-generating circuit in response to a first clock signal, the first toggle signal having one of a first positive shape, a null shape, and a first negative shape for each cycle of the first clock signal; multiplying the first toggle signal by a first coefficient signal to create a first intermediate signal; generating a second toggle signal at a second signal-generating circuit in response to the first clock signal, the second toggle signal having one of a second positive shape, the null shape, and a second negative shape for each cycle of the first clock signal; multiplying the second toggle signal by a second coefficient signal to create a second intermediate signal; and generating a first output signal by adding the first intermediate signal and the second intermediate signal together, wherein the first and second positive shapes are each a positive square-wave half cycle, wherein the first and second negative shapes are each a negative square-wave half cycle, wherein when the first toggle signal has one of the first positive shape or the first negative shape, the second toggle signal has the null shape, and wherein when the second toggle signal has one of the second positive shape or the second negative shape, the first toggle signal has the null shape.
