In this paper, an accurate and low-cost method for on-wafer noise figure measurement, specifically designed for low-noise amplifiers (LNAs), will be proposed. An experiment conducted on a 5 GHz LNA demonstrates that a good agreement can be reached between the measurement result of the proposed method and that of a commercial noise parameter measurement system.
