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…

Detecting Critical Resonances in Microwave Amplifiers through Noise Simulations
Juan-Mari Collantes, Nerea Otegi, Aitziber Anakabe +3
The presence of critical resonances in microwave power amplifiers has a negative impact on its behavior and performance. These critical resonances are usually predicted from pole-z…

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…
