Efficient Calculation of Stabilization Parameters in RF Power Amplifiers
Libe Mori, Ibone Lizarraga, Aitziber Anakabe +3
This paper proposes an efficient method for the calculation of the stabilization parameters in RF power amplifiers operating in periodic large-signal regimes. Stabilization is achi…
Pole-Zero Identification: Unveiling the Critical Dynamics of Microwave Circuits Beyond Stability Analysis
Juan-Mari Collantes, Libe Mori, Aitziber Anakabe +5
Pole-zero identification refers to the obtaining of the poles and zeros of a linear (or linearized) system described by its frequency response. This is usually done using optimizat…
In-Circuit Characterization of Low-Frequency Stability Margins in Power Amplifiers
Jose Manuel Gonzalez, Nerea Otegi, Aitziber Anakabe +3
Low-frequency resonances with low stability margins affect video bandwidth characteristics of power amplifiers. In this work, a non-connectorized measurement technique is presented…
Understanding the Effect of Long-Term Memory Model Parameters in Pole-Zero Identification for Stability Analysis of Power Amplifiers
Libe Mori, Aitziber Anakabe, Juan-Mari Collantes +1
Understanding the nature of potential instabilities is indispensable for the stabilization of power amplifiers. Pole-zero identification is one of the techniques that can be used t…
