Inductors are critical components in RF applications, such as filters, oscillators, and amplifiers. However, integrated spiral inductors on silicon (Si) have shown performance limitations. They do not meet the challenges of current trends toward miniaturized, low-cost, and on-chip multistandard communication systems [1]. While they have good performance in terms of noise, linearity, and power consumption, as they do not need a dc bias to work, electromagnetic interference with neighboring circuitry is a major problem associated with the layout of spiral inductors.

基于 Gyrator-C 的 CMOS 有源电感器：性能优化技术分析


电感器是射频应用中的关键元件，例如滤波器、振荡器和放大器。然而，硅 (Si) 上的集成螺旋电感器已显示出性能限制。它们无法应对当前小型化、低成本和片上多标准通信系统趋势的挑战[1]。虽然它们在噪声、线性度和功耗方面具有良好的性能，但由于它们不需要直流偏置即可工作，但与相邻电路的电磁干扰是与螺旋电感器布局相关的主要问题。
