Abstract
A triangle waveform generator for a pulse-width amplitude multiplier includes a digital-to-analog converter and a charge transfer network. Clocked signals applied to the converter, which includes a resistor chain for providing a set of different potentials, sequentially select ones of the potentials and supply two of them to the charge transfer network. The network weights each of the potentials received, then combines them at an output node. By employing appropriate clocking of the converter, a triangular waveform having a plurality of discrete steps results.
