This paper presents the design and realization of a 15-bit-input-Digital-to-Analog Converter (DAC) that leverages the advantages of both Delta-Sigma Modulation (DSM) and Current-Steering DAC (CS-DACs) architectures to achieve superior dynamic performance. The proposed DAC design partitions the digital input signal into two segments: The 7- least significant bits (LSBs) are processed through a Delta-Sigma Modulator (DSM) based on a 3-stage cascaded MASH (Multi-stage Noise Shaping) structure, generating 3-bit modulated output. The 8- most significant bits (MSBs) are decoded utilizing a thermometer coding scheme, yielding 31 control signals for 8x current sources and 7 control signals for 1x current sources. By integrating the DSM DAC with a CS-DAC, the proposed architecture realized a 8-bit DAC, achieving significant improvements in dynamic performance compared to a conventional 8-bit CS-DAC. The results demonstrate enhanced resolution and reduced noise, underscoring the efficacy of the combined approach in addressing the limitations inherent in standalone Current-Steering DACs.
