Description
In recent years,system-on-chip (SoC) to integrate analog and digital circuits on the same chip is proceeding with the development of CMOS miniaturization technology.A digital-to-analog Converter (DAC) used in audio equipment, etc. which are demanded higher accuracy. In this paper a delta-sigma modulator with FIR-filter using Jitter Shaper (JS) is proposed to realize highly accurate DAC. Disadvantages of the conventional approaches, and theoretical effectiveness of proposed method is shown using the MATLAB / Simulink simulation. Key Words : FIR-filter, Digital to Analog Converter, Delta-sigma DSM, Jitter Shaper
