为了实现整形脉冲调节的智能化,用计算机分别控制多个GaAs场效应管栅极偏压,并对场效应管产生的脉冲进行脉冲叠加,以控制整形电脉冲的形状;为提高输出整形脉冲的稳定性并减小触发晃动时间,优化设计了脉冲整形电路,结果表明:脉冲输出幅度1～5V可调;方波脉冲输出宽度0～3ns;脉冲前后沿分别为250ps和350ps;幅度稳定性:～4%(峰峰值);时域调整精度200ps. In order to intelligently modulate the pulse shaping, a computer is used to control the gate bias of a plurality of GaAs FETs, respectively, and the pulses generated by the FETs are pulse superposed to control the shape of the shaping pulse. In order to improve the output shaping pulse The results show that the amplitude of pulse output is adjustable from 1 to 5V, the width of square wave pulse output is from 0 to 3ns, and the pulse front and back are 250ps and 350ps respectively. Amplitude stability: ~ 4% (peak-to-peak); time-domain adjustment accuracy of 200ps.
