基于双探头电感耦合方法，提出了一种在直流偏置条件下测量任意无源元件（R、L或C）阻抗的新方法。通过预测量校准过程，该方法能够消除由于测量设置引起的误差。使用电阻和电感作为测试器件，以良好的精度演示了高达1ghz的元件的阻抗特性。该方法提供了关键电路元件在其预期偏置条件下的阻抗行为，从而可以根据特定偏置条件正确选择元件，以实现最佳电路性能。
Based on a two-probe inductive coupling approach, a novel measurement method to characterize the impedance of any passive component (R, L, or C) under a direct-current (dc) biasing condition has been developed. With a premeasurement calibration process, the proposed method has the ability to eliminate errors due to the measurement setup. Using resistors and inductors as devices under test, impedance characterization of a component up to 1 GHz with good accuracy has been demonstrated. The proposed method provides insight of the impedance behavior of a critical circuit component under its intended biasing condition, so that proper choice of a component can be made for a specific biasing condition to achieve optimal circuit performance.
