A Sigma-delta DAC with a Fully-Differential Current-Mode Semidigital Postfilter
완전차동 전류모드 준디지털 포스트필터를 사용하는 시그마-델타 DAC
Abstract
This paper introduces a sigma-delta DAC with a fully-differential current-mode semidigital IFIR postfilter. A proposed fully-differential postfilter exhibits not only an improved SNR(signal-to-noise ratio) but also a reduced opwer dissipation.
