摘要

提出了一种新的旋涡电容有源电感实现电路方案。旋转器是使用两个实例的±90%宽范围微调晶体管实现的。该晶体管是围绕一个不平衡电流反射镜作为调谐元件而构建的。为了在电流镜的VGS回路上产生不平衡，将直流电流注入电阻。该结构的等效电感可在1mH ~ 450mH范围内调节。

A tunable gyrator-capacitor active inductor

A new circuit solution for a gyrator-capacitor active inductor implementation is proposed. The gyrator is implemented using two instances of a ±90% wide range fine tuning transconductor. The transconductor is built around an unbalanced current mirror used as tune element. A DC current is injected into a resistor in order to create an unbalance on the VGS loop of the current mirror. The equivalent inductance of the structure can be adjusted from 1mH to 450mH.
