该论文提出了一种基于增量电荷基DAC的发射机，工作在10位分辨率、128MS/s采样率，实现了-155dBc/Hz的带外噪声性能，旨在去除级间SAW滤波器并满足FDD LTE/WCDMA等高阶调制对噪声和线性度的严格要求，同时采用数字密集型架构提升系统鲁棒性并降低功耗和面积。
stringent requirements on every transmitter design aspect. Especially when the inter-stage SAW filter is removed, FDD operation using high-order modulation schemes (as in e.g. WCDMA, LTE) demands both remarkable noise performance and linearity, which is difficult to achieve without sacrificing power consumption. On the other hand, the increased switching speed of nanoscale MOS transistors has enabled the implementation of various digital-intensive TX architectures [1-5], that improved system robustness and reduced power and area consumption even in face of decreased supply voltages. However, in these cases reconstruction filtering is hindered by direct digital-to-RF conversion, leading to increased quantization noise and strong sampling aliases. Often
