Abstract
A device and method are disclosed for synthesizing a waveform having pulse segments. An exemplary generator can include units having a time delay element and pulse generator generating the pulse segments. An input divider divides an input signal into signal instances that propagate through the units and an output combiner combines pulse segments to form the waveform. The pulse generators include a sharpening circuit for sharpening a rising edge and a falling edge of the pulse segments. The sharpening circuit includes a tunable delay element coupled to a non-linear transmission line (NLTL). Another NLTL can be coupled in parallel with the tunable delay element and the first NLTL. The NLTLs include input sections coupled to anodes or cathodes of Schottky diode elements, and the respective cathodes or anodes are coupled to a signal ground.
