Top-Down Design for MASH21 Sigma-Delta Modulator
摘要
Abstract
The authors propose a top-down design process for MASH21 modulator. In system level, coefficient scaling is used to limit integrator＇s output; in circuit level, integrator transient modeling is used to analyze the effect caused by OP＇s non-ideality, and get the optimized design region for SNR, area and power. A MASH21 modulator for digital audio application is designed to verify the proposed design criteria. This experimental prototype is implemented with TSMC18MMRF, operates under a single 1.8 V power supply, and achieves a measured SNDR of 91dB.关键词
