Digital-to-Analog Converters with Arbitrary Radix and a Single Reference Source


There are DAC structures available in the literature for radix r = 2, 3 and 4, but how they are arrived at is missing. Author’s generalized DAC of any radix reported recently removes this gap, but requires r − 2 references sources. This paper gives three methods of replacing all the reference sources, except one. Comparison of all the three methods is given.
