摘要

一个过采样带通级联数模转换器，包括数字FIR和模拟半数字滤波，以减少带外量化噪声，已集成在0.25-/spl μ m CMOS技术。该转换器在6.25 mhz以50-MHz为中心的信号频带内具有83 dB的动态范围，抑制带外量化噪声40 dB。

A CMOS oversampling bandpass cascaded D/A converter with digital FIR and current-mode semi-digital filtering

An oversampling bandpass cascaded digital-to-analog converter, including digital FIR and analog semi-digital filtering to reduce out of band quantization noise, has been integrated in 0.25-/spl mu/m CMOS technology. The converter has 83 dB of dynamic range for a 6.25-MHz signal band centered at 50-MHz and suppresses out-of-band quantization noise by 40 dB.
