浮地频变负阻新电路与无源LC梯形滤波器的FDNR直接模拟

A Novel Realization of Floating FDNR and FDNR Straightward Simulation of Passive LC Ladder Filters

本文提出的浮地频变负阻新电路具有有源和无源元件少、灵敏度低、稳定性好、无需调整和易于实现等优点。它的提出,不仅解决了一般浮地频变负阻(FDNR)元件的实现问题,而且解决了直接模拟LC梯形滤波器的低灵敏度FDNR滤波器实现问题。

A novel realization of floating FDNR proposed in the paper has advantages such as fewer passive and active elements, lower sensitivity, good stability, no need of adjustment, easy realization. The realization proposed has resolved not only the problem of realization of general floating FDNR elements, but also the realization of low sensitivity FDNR filters which simulate LC ladder filters straightforwardly.
