ABSTRACT:
A digital-analog converter comprises a reference value adder having its multidigit input coupled to a multidigit output of a switch unit and a Fibonacci p-code convolution unit. The fibonacci p-code convolution unit has its multidigit output coupled to a multidigit input of the switch unit. The Fibonacci p-code convolution unit comprises n stages, each of which, related to a certain bit position in a range from one to n-2, comprises an AND gate and an OR gate. Each of the stages corresponding to bit positions from zero to n-1 comprises a flip-flop, an OR gate and an AND gate. The set and reset inputs of the flip-flop of each stage are coupled, respectively, to the output of the AND gate and to the output of the OR gate. The set input of the flip-flop of the stage of the zero bit position is a counting input of the digital-analog converter. First and second inputs of the OR gate of the stage of the ith bit position are coupled, respectively, to the outputs of the AND gates of the (i+l)th and (i+p+l)th states. First, second and third inputs of the AND gate of the ith stage, beginning with the (p+l)th stage, are coupled, respectively, to the reset output of the flip-flop of the same stage, to the set output of the flip-flop of the (i-l)th stage and to the set output of the flip-flop of the (i-p-l)th stage. The remaining inputs of all the AND gates are joined together to constitute a clock input of the digital-analog converter, where n is the length of the Fibonacci p-code and i=0,1,2, . . . , n-l.
