    • PURPOSE:To generate an output signal comprising an accelerated potential difference on other signal line by turning on a switch circuit of a source output when a voltage change being a threshold value or over exists to a gate of a transistor (TR) connected to one of signal line pairs so as to activate a flip- flop. CONSTITUTION:After signal line pairs 1, 2 are precharged to a high level, a signal detection circuit 7 is operated, a minute signal appears on the signal line pairs 1, 2, one signal line, e.g., the signal line 2 changes from a high level to a low level gradually and the potential of the signal line 2 is decreased by a threshold voltage's share of a TR 8, then the TR 8 is turned on. Then the charging of a node 11 discharged by a TR 9 is started so as to turn on an extracting TR 5. Thus, the flip-flop 4 starts operation to accelerate rapidly the potential change in the signal line pairs 1, 2.
    • 目的:当电压变化为阈值或更高的电压变化存在于连接到其中一个的晶体管(TR)的栅极时,通过接通源极输出的开关电路来产生包括其他信号线上的加速电位差的输出信号 信号线对,以激活触发器。 构成:在信号线对1,2被预充电到高电平之后,信号检测电路7被操作,信号线对1,2上出现微小的信号,一条信号线,例如信号线2从 高电平到低电平,并且信号线2的电位降低TR 8的阈值电压份额,则TR 8导通。 然后开始由TR9放电的节点11的充电,以便导通提取TR5。因此,触发器4开始操作以迅速加速信号线对1,2的电位变化。

    • PURPOSE:To ensure the operation of an AND-OR basic circuit using a GaAsFET by applying a clock signal and an inverted clock signal to the control input terminal of a transistor TR. CONSTITUTION:TRs Q21, Q22, Q23, and Q24 and level shift diodes connected to them are used for the purpose of matching the signal level in connection between elements. When all of the clock signal is applied to low-voltage sides B1, C1, B2, and C2 of an AND circuit, the clock signal is set to an optimum level as shown in a figure B by TRs Q25, Q26, Q27, Q28, Q30, and Q31 and level shift diodes D1 and D2. In this case, the operation is ensured because a DC operation is ensured because a DC operation level is matched in operations of a frequency divider and a mixer, and this device can be applied to the circuit where the AND circuit using, especially, a GaAsFET is a basic component.
    • 目的:通过将时钟信号和反相时钟信号施加到晶体管TR的控制输入端,确保使用GaAsFET的AND-OR基本电路的工作。 构成:连接到它们的TRs Q21,Q22,Q23和Q24以及电平移位二极管用于匹配元件之间的信号电平。 当所有时钟信号都加到“与”电路的低电压侧B1,C1,B2和C2时,时钟信号被设置为最佳电平,如图B所示,TRs Q25,Q26,Q27,Q28 ,Q30和Q31以及电平移位二极管D1和D2。 在这种情况下,由于在分频器和混频器的操作中DC操作电平匹配,所以确保了DC操作,并且该装置可以应用于使用特别是GaAsFET的AND电路的电路 是一个基本的组成部分。
