A method (1300) is provided for generating one or more waveforms (130, 140). The method includes: generating a first toggle signal (1130, 1330) in response to a clock signal (1110), the first toggle signal having one of a first positive shape, a null shape, and a first negative shape for each cycle of the clock signal; multiplying the first toggle signal by a first coefficient signal to create a first intermediate signal (1440); generating a second toggle signal (1140, 1330) in response to the 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 clock signal; multiplying the second toggle signal by a second coefficient signal to create a second intermediate signal (1440); and generating a first output signal (1170) by adding the first intermediate signal and the second intermediate signal together (1350).
