Selection of the calculus system base for ADC and DAC with weight redundancy

Abstract

It is well known that the application of the weight redundancy in self-calibrating DAC enables to lower considerably, the requirements regarding the accuracy of digits weight formation, particularly in multidigit code-current converters and the idea of laser adjustment of the resistor matrices nominals. It is also known, that the construction of ADC of the bit-wise balancing on the base of such DAC additionally enables to increase (by an order or more) the operation speed as a result of a considerable reduction of the balancing cycle duration
