摘　　要：设计了一种新的产生RSFQ时钟信号的电路,并利用W IN S软件对电路进行了模拟.它可以产生连续脉冲,脉冲的周期由电路中约瑟夫林传输线的长度决定,可以产生周期约10 ps的连续脉冲.经过扩展,这种电路能通过输入触发脉冲实现振荡的停止,从而产生固定个数的时钟信号,产生时钟信号的数目由启动信号和停止信号的时间差决定;在电路中使用多路开关,还可以在不改变硬件电路的条件下,通过输入触发信号来改变输出时钟信号的周期.A new type of timing pulse generator is designed and simulated using WINS software. The periods of the continuous pulses is determined by the length of Josephson transmission line in the circuit. Continuous pulse periods of about 10 ps can be generated. By improving, the generator can be stopped by a pulse input to generate an anticipant number of pulses. The number is determined by the time interval between ＇START＇ and ＇STOP＇ signal. Taking advantage of Multiplexer, it can generate pulses with different periods without changing the hardware.
