摘要
文中介绍三种射频LNA的电路结构。inductivedegeneratecascode结构具有很好隔离度、低噪声及高增益而普遍使用,在此基础上介绍高稳定度的LNA结构和低功耗的偏置电流复用结构。
Three kinds of circuit architecture of radio frequency low noise amplifier are introduced. Inductive- degenerate cascode architecture is widely used for its high gain, low noise figure and good isolation between input and output. Based on this circuit, a highly stable LNA structure and a bias current reuse structure to reduce power dissipation are presented.
