    • A superconductive large-scale integrated circuit chip comprises a plurality of pads, a superconductive line which short-circuits respectively adjacent pairs of the pads, and an input buffer circuit. The input buffer circuit includes a Josephson junction which is either in a superconducting state or a finite voltage state in response to a magnetic field established by current that is supplied to the superconductive line by flowing in from one of the two pads and flowing out from the other pad. The input buffer circuit wave-shapes the externally supplied signal into an amplitude-controlled signal, and the latter signal is led by a superconductive line to a circuit within the chip which requires the signal. Even when the external signal current has become abnormally great due to noise, etc., any circuit situated halfway within the chip can be prevented from malfunctioning from the magnetic flux generated by the large current.

    • In a constant current circuit, a constant current is caused to flow through a resistor, thereby causing a constant voltage to occur across the resistor. This constant voltage is then superimposed on an output signal of an operational amplifier that is to be fed back to the drain of a field effect transistor, thereby maintaining the same potential in an AC manner between the output terminal of the operational amplifier and the drain of the field effect transistor. In this way, the gate and drain of the field effect transistor is caused to exhibit the same potential in an AC manner, so that no current will occur through the stray capacitance between the gate and drain of the field effect transistor. As a result, similarly to a case of using a feedback capacitor, the input impedance of the field effect transistor can be raised.
    • 在恒流电路中,使恒定电流流过电阻器,从而在电阻器两端产生恒定的电压。 然后将该恒定电压叠加在要反馈到场效应晶体管的漏极的运算放大器的输出信号上,从而在运算放大器的输出端和漏极之间以AC方式保持相同的电位 场效应晶体管。 以这种方式,使场效应晶体管的栅极和漏极以交流方式呈现相同的电位,使得不会通过场效应晶体管的栅极和漏极之间的杂散电容发生电流。 结果,与使用反馈电容器的情况类似,可以提高场效应晶体管的输入阻抗。
