摘要
本文提出了一种采用0.13 um CMOS工艺实现的10位宽带笛卡尔相位旋转器，该旋转器具有新颖的线性数字VGA。VGA拓扑对器件建模不确定性和PVT变化具有鲁棒性。系统提供7.8 dB电压增益，-3 dB带宽为7.6 GHz。当相移范围为360°，32个相移步为11.25°时，最大相位误差为2°。补偿不匹配正交输入的能力也得到了证明。
This paper presents a 10-bit wideband Cartesian phase rotator with a novel linear digital VGA implemented in a 0.13 um CMOS process. The VGA topology is robust to device modeling uncertainties and PVT variations. The system provides 7.8 dB voltage gain with -3 dB bandwidth of 7.6 GHz. A maximum phase error of 2deg has been achieved for a phase shifting range of 360deg with 32 phase steps of 11.25deg. The capability to compensate for mismatched quadrature inputs is also demonstrated.
