该论文提出了一种阻抗变换N-path滤波器，能够实现被动电压增益，解决了传统电感/变压器在硅基集成中面积大、品质因数低和调谐困难的问题。通过利用线性周期时变（LPTV）N-path结构，实现了新的滤波和阻抗变换功能。
The four main passive circuit elements include the resistor, capacitor, inductor, and transformer. Inductors and transformers have been notoriously challenging to integrate in silicon, and they occupy a significant chip area. The limited metallization and conductive substrate result in a poor quality factor (Q) and limited self-resonance frequency. The tuning of inductor-based resonators is further challenged by the limited tuning range and Q of switched-capacitors/inductors. Recent LPTV N-path structures have demonstrated new functionalities that address some of these challenges, such as equivalent second-order LC bandpass filtering, lowpass filtering, notch filtering, and non-magnetic nonreciprocity [1-5]. Transformers face additional challenges of limited coupling coefficients, especially when a large turns ratio is desired [6], but they are critical to impedance transformation and matching networks.
