Using reciprocity theorem to analyze R-2R network DACs

Abstract

Abstract. Reciprocity theorem is proposed to design and analyze R-2R based DAC, which can make the complicated design and analysis of R-2R based DACs simple. The detail of how to use reciprocity theorem in the design and analysis of R-2R based DAC is given. The 14-bit DAC designed by Reciprocity Theorem has performances of 69dB SNR, 11.1 bits ENOB and 77.9dB SFDR.
