Abstract
An arrangement for generating a voltage waveform having a triangular shape, in which a first voltage waveform having a sawtooth shape is added to a second voltage that has a sawtooth shape with horizontal components during predetermined intervals of the second voltage waveform. A biased diode bridge applies the horizontal components to the second voltage waveform, which has peaks equal to the peaks of the first voltage waveform. Upon adding the first and second voltage waveforms, a voltage waveform with triangular shape is generated.
