A Methodology for Generating Controllable High-Speed Pulses

Abstract A methodology for generating high-speed pulses is discussed in this paper. In this scheme, the generation of high-speed pulses is transformed into the generation of controllable DC voltage and frequency information of pulses and into the pulse composition. The controllable DC level controls the level of high and low levels of pulses. The frequency information of pulses is generated by programmable data sequence which controls the pulse width and delay. The rising- and falling-times of pulses are adjusted through changing the charging and discharging currents of the synthesizing pulse circuit. The generated pulse is specified by the minimum pulse width: 5 ns, the maximum swing: 7 V, the accuracy of pulse level: 0.1 V, and the rising or falling transition time: 2 ns.
