摘要

A 4-bit continuous-time delta-sigma modulator (CT-DSM) with the proposed data-weighted averaging (DWA) algorithm for audio application is presented. The proposed method randomly adds one to pointer address in the DWA to reduce distortion tones and improve the performance of spurious-free dynamic range (SFDR) and signal to noise and distortion ratio (SNDR), as compared with the conventional DWA. The post-layout simulation results show that the modulator designed in TSMC 0.18 μm CMOS process achieves the SNDR of 81.5 dB and the dynamic range (DR) of 85dB in 24 kHz signal bandwidth. The chip area is 1.168 × 0.632 mm² and the power consumption is 339 μW from a 1.8 V power supply.
