A Novel Hybrid Analysis Approach for Subharmonic Self-Oscillating Mixers Combining Volterra Series and Conversion Matrix Methods

In this paper a novel analysis method for subharmonic self-oscillating mixers (SOMs) is presented. It suggests a hybrid approach combining Volterra series analysis describing the oscillating steady-state condition and a conversion matrix method analysing the higher-order mixing phenomena. It eliminates the limitation of increasingly complex analytical description for high orders and is therefore an excellent choice for high-order subharmonic SOMs. The proposed method is applied to a balanced subharmonic SOM circuit and yields an excellent performance prediction.
