    • Disclosed is a low power consuming logic circuit to restrain a short circuit current which flows within an inverter circuit of an inverter having a clock input connected behind a pass-transistor logic circuit. In the logic circuit, the inverter having a clock input is provided on the output of a pass-transistor logic circuit. The inverter having a clock input includes the inverter circuit and write control means. A data holding circuit is connected to the output of the write control means. In the logic circuit, a clock is input to the inverter having a clock input after the output of the pass-transistor logic circuit is stabilized. Thus, the short circuit current which flows in the inverter circuit is restrained. In addition to the logic circuit, a positive feedback circuit for supplying an inverted signal from the inverter circuit to the output of the inverter having a clock input can be provided. In the logic circuit, the positive feedback circuit functions to further increase the voltage of the output signal of the pass-transistor logic circuit if it is higher than the input threshold of the inverter, and to further reduce the same voltage if it is lower than the input threshold of the inverter. Consequently, the short circuit current flows in the inverter having a clock input in a very short time.
    • 公开了一种低功耗逻辑电路,用于抑制在具有连接在传输晶体管逻辑电路后面的时钟输入的反相器的反相器电路内流动的短路电流。 在逻辑电路中,具有时钟输入的反相器设置在传输晶体管逻辑电路的输出端。 具有时钟输入的逆变器包括逆变器电路和写入控制装置。 数据保持电路连接到写入控制装置的输出。 在逻辑电路中,在通过晶体管逻辑电路的输出稳定之后,时钟输入到具有时钟输入的反相器。 因此,抑制在逆变器电路中流动的短路电流。 除了逻辑电路之外,还可以提供用于将来自逆变器电路的反相信号提供给具有时钟输入的反相器的输出的正反馈电路。 在逻辑电路中,如果反馈电路的输入阈值高于反相器的输入阈值,则正反馈电路用于进一步增加通过晶体管逻辑电路的输出信号的电压,如果低于 逆变器的输入阈值。 因此,短路电流在非常短的时间内具有时钟输入的逆变器中流动。
