快电子学低晃动触发电路和宽带放大器的研究与分析

LOW JITTER TRIGGER CIRCUIT AND WIDE BAND AMPLIFIER OF FAST ELECTRONICS

研究了快电子学中２种最常用的单元电路：低晃动的触发电路和宽带放大器。对降低触发电路延迟时间晃动的方法进行了详细分析，并在实验中验证了这些方法，触发电路延迟时间晃动小于４５ｐｓ。对宽带放大器的一些基本特性及提高宽带放大器带宽的方法进行了分析，并应用于实际工作中，输出幅度±１０Ｖ，带宽大于２００ＭＨｚ。

Two circuit of fast electronics:trigger circuit and wide band amplifier are described.The method of lowering the delay time jitters of the trigger circuit is discussed.The delay time jitter is less than 45 ps.The character and the method of increasing the band width of the wide band amplifier are described. When the output amplitute is ±10 V, the band width approaches 200 MHz.
