Design methodology of analog circuits for a digital-audio-signal processing 1-bit ???? DAC
디지털 오디오 신호처리용 1-bit Δ$\Sigma$ DAC 아날로그 단의 설계기법
Abstract
The performance of a 1-bit DAC depends on that of the analog circuits. The mixed SC-CT (switched capacitor-continuous time) architecture is an effective design methodology for the analog circuits. This paper Proposes a new buffer scheme for the 1-bit digital-to-analog subconverter and a new SF-DSC(smoothing filter and differential-to-sig le converter) which performs both the smoothing filter and the differential-to-single convertor simultaneously.
