Abstract

PURPOSE:To largely reduce the amount of current supplied to a reference potential terminal, by connecting the reference potential terminals and a power source at a higher potential than said reference potential with a resistor. CONSTITUTION:In a resistor network potential circuit, when a reference potential below the potential at the power source thereof is needed, the current supplied to the reference potential terminals is not supplied from the reference potential source, but the greater part thereof is supplied from said power source by connecting the reference potential point and said power source with a proper resistor. In other words, when the voltage of the power source is VS and that of the reference potential source is VR, the value of the resistors Rd is to be Rd=(Vs-VR)/IR so that only a current IR flows. Consequently, no current is supplied to the terminal VR. However, there is a slight fluctuating width in the voltage applied to the power source terminals VS and -VS, therefore, a current of DELTAVS/Rd in supplied to the terminal VR, but the value of said current is sufficiently small. By such a constitution, it is possible to largely reduce the amount of the current from the reference potential source.
