Digital-to-analog converter

Abstract

Abstract A DIGITAL-ANALOG CONVERTOR INCLUDING A REGISTER, A RESISTIVE NETWORK, AND AN AMPLIFIER CIRCUIT. THE REGISTER INCLUDES A FIRST SET OF FLIP-FLOPS THAT PROVIDES DIGITAL OUTPUT SIGNALS IN A REPETITIOUS, ASCENDING ORDER, BINARY COUNT SEQUENCE AND A SECOND SET OF FLIP-FLOPS THAT PROVIDES INDIVIDUAL OUTPUT SIGNALS CORRESPONDING TO THE INDIVIDUAL REPETITIONS OF THE FIRST SET OF FLIP-FLOPS. THE RESISTIVE NETWORK INCLUDES A PLURALITY OF BINARY WEIGHTED RESISTORS THAT ARE COUPLED TO RECEIVE THE OUTPUT SIGNALS PROVIDED BY THE FIRST SET OF FLIP-FLOPS AND A PLURALITY OF EQUALLY WEIGHTED RESISTORS THAT ARE COUPLED TO RECEIVE THE OUTPUT SIGNALS PROVIDED BY THE SECOND SET OF FLIP-FLOPS. ALL BUT ONE OF THE BINARILY WEIGHTED RESISTORS HAVE A COMMON OUTPUT TERMINAL FOR PROVIDING A FIRST SUMMING SIGNAL AND ALL OF THE EQUALLY WEIGHTED RESISTORS AND ONE OF THE BINARILY WEIGHTED RESISTORS HAVE A COMMON OUTPUT TERMINAL FOR PROVIDING A SECOND SUMMING SIGNAL. AN AMPLIFIER CIRCUIT IS COUPLED TO RECEIVE THE FIRST SUMMING SIGNAL AND THE SECOND SUMMING SIGNAL FOR PROVIDING AN ANALOG OUTPUT SIGNAL BEING DIFFERENTIALLY RELATED TO THE RECEIVED SUMMING SIGNALS.
