Methodology for Fast Edge Compression Based on SRD
Fast edge pulses play a critical role in response testing and are widely used, and step recovery diode (SRD) based designs are a dominant form of their generation. However, the conventional method based on SRD and constant voltage source has the drawback of fixed amplitude. In this paper, a novel design of a fast edge compression circuit based on one SRD and two constant current sources is proposed. The fast switching characteristics of the Schottky diode are used to transmit the step characteristics of the SRD to generate a fast edge signal. One constant current source controls the amplitude and the other constant-current source is used to optimize the waveform quality. The experimental results show that the rise time of the pulse edge is about 140ps and the amplitude can be continuously controlled between 50mV and 3.0V.
