摘要：A circuit and method for converting a digital number to an analog output signal,wherein the most significant bit or \"sign\" bit of the digital number is used for switchingthe accumulated currents of the other data bits to a chain of operational amplifiersemploying feedback resistors for conversion into an output voltage of magnitude andsign corresponding to the input digital number. A decoding circuit and method enablesthe circuit to present an output voltage corresponding to the two's--complement of theinput digital number.
