基于对有源混频器噪声机理的物理认识，提出了一种减小开关闪烁噪声贡献的消噪技术。为了验证概念，制作了0.13 /spl mu/m CMOS双平衡混频器原型。该电路实现了几乎比标准实现低一个数量级的闪烁噪声角，而在线性度、增益或功耗方面没有任何损失。
Based on the physical understanding of noise mechanisms in active mixers, a noise cancellation technique to reduce the flicker noise contribution of the switches in a Gilbert-type mixer is presented. For the proof of concept, a prototype double-balanced mixer in 0.13 /spl mu/m CMOS is fabricated. The circuit achieves a flicker noise corner of almost an order of magnitude lower than that of a standard implementation, without any penalty in the linearity, gain, or power consumption.
