Abstract. Schematic of voltage-digital converter with summation of equal currents at ladder-type attenuator is proposed. The converter may be used in feedback circuit of precision digital voltmeter. Experiments carried out with a four-decade converter give ratio error of less than 0,01 %.
Keywords: digital voltmeter, voltage-digital converter.
