On the Output Resistance of Self-Checking Voltage Dividers

Abstract
This paper deals with the computation of the variable output resistance of Cutkosky's self-checking binary voltage divider. For an N-bit divider, the maximum output resistance was found to increase with N at the rate of N/9 times the divider's characteristic input resistance. To increase the divider's resolution while limiting its output resistance, a binary potentiometer as a termination is suggested.
