Abstract
An arbitrary waveform generator (AWG) generates an output signal that linearly ramps between discrete levels to approximate a smoothly varying waveform. The AWG includes a digital-to-analog converter (DAC) formed by a set of N ramp generators, with each ramp generator producing output currents that ramp at adjustable rates between discrete levels in response to a change in state of an input waveform data bit. The output currents of all N ramp generators of the DAC, which have separately weighted magnitude levels, are summed and converted to a proportional voltage to produce the AWG's output signal.
