چکیده :

This review investigates N-path filters as a burgeoning technology for integrated tunable filtering applications. N-path filters have garnered significant interest due to their superior performance including linearity, power transfer efficiency, tunability, and Q-factor. This work delves into recent advancements within the field of N-path filters, focusing on the performance, analysis, circuit design improvements, emerging applications, and potential avenues to filter redesign. This work presents two redesigned filters: the first operates from 0.1 to 1 GHz with a 20 MHz bandwidth and -6.818 dB gain. The second operates from 50 MHz to 1.5 GHz with a fixed 20 MHz bandwidth, 9.5 dBm linearity, and 13.5 mW power consumption.
