    • An analog delay circuit which includes an analog memory circuit wherein a plurality of memory cells each including a memory capacitor and a selection switch for the memory capacitor are arranged in a matrix includes row switches provided for the individual columns for individually being driven by row selection signals. A same clock signal from a clock generation circuit is supplied commonly to an X direction scanning circuit and a Y direction scanning circuit. The number of stages of registers of the X direction scanning circuit and the number of stages of registers of the Y direction scanning circuit are set so that they have no common divisor other than 1. Consequently, when the memory cells are to be selectively scanned, a same selection condition can be provided to all of the memory cells without relying upon the positions of the memory cells, and the parasitic capacitance connected to a signal write/read terminal is reduced.
    • 一种包括模拟存储电路的模拟延迟电路,其中包括存储电容器和用于存储电容器的选择开关的多个存储单元被布置成矩阵,包括为各个列提供的行开关,用于单独由行选择信号驱动 。 来自时钟发生电路的相同时钟信号被共同地提供给X方向扫描电路和Y方向扫描电路。 将X方向扫描电路的寄存器的级数和Y方向扫描电路的寄存器的级数设置为除了1以外没有公共除数。因此,当要选择性地扫描存储器单元时, 可以在不依赖于存储单元的位置的情况下向所有存储单元提供相同的选择条件,并且减少连接到信号写/读终端的寄生电容。

    • A logic circuit adapted for fabrication as an integrated circuit is formed having a differential amplifier operating with a constant current source and an appropriate voltage source, and having output transistors to provide the necessary output voltages, does not require a reference voltage input to the differential amplifier, thus, reference voltage transistors are not required. The two binary input signals are selected to have the same amplitude difference between the high and low levels thereof and one of the two input signals is shifted relative to the other one by the amount substantially equal to 1/2 the selected amplitude difference, and the output signals are similarly level shifted. Using this basic logic circuit as a building block other, more complex, logic circuits can be obtained.
    • 适用于作为集成电路制造的逻辑电路形成为具有用恒定电流源和适当电压源工作的差分放大器,并且具有输出晶体管以提供必要的输出电压,不需要将参考电压输入到差分放大器 因此,不需要参考电压晶体管。 选择两个二进制输入信号在其高电平和低电平之间具有相同的幅度差,并且两个输入信号中的一个相对于另一个输入信号相移大约等于所选择的幅度差的1/2, 输出信号类似地电平移位。 使用该基本逻辑电路作为构建块,可以获得更复杂的逻辑电路。
