Abstract

Alternative circuit designs concerning the simulation of floating lossy inductors using voltage differencing buffered amplifiers (VDBAs) are described. The topologies proposed here require only three VDBAs and one capacitor to simulate a floating inductance with series and parallel resistance. The simulated equivalent elements, namely equivalent resistance (R_eq) and equivalent inductance (L_eq) are electronically controllable through the external bias currents of the VDBAs. The VDBA non-idealities including transconductance inaccuracy and voltage transfer error on the performance of the circuits has been discussed in detail. To support the theoretical analysis and demonstrate the practical workability of the proposed synthetic inductors, PSPICE simulation and experimental test results are also reported.

用差动缓冲放大器模拟可调谐浮动损耗电感的无电阻实现。

摘要

描述了有关使用压差缓冲放大器（VDBA）的浮动有损耗电感器仿真的替代电路设计。这里提出的拓扑仅需要三个VDBA和一个电容器来模拟具有串联和并联电阻的浮动电感。模拟的等效元件，即等效电阻（R _eq）和等效电感（L _eq））可通过VDBA的外部偏置电流进行电子控制。已经详细讨论了VDBA的非理想性，包括跨导误差和电压传输误差对电路性能的影响。为了支持理论分析并证明所提出的合成电感器的实际可操作性，还报告了PSPICE仿真和实验测试结果。
