Abstract
Dynamic off-state stress for RF applications is investigated via integrated test circuits to enable GHz level testing. We have performed characterization of test circuits to ensure the dynamic stress signal waveform integrity, which is verified against model simulation data. We report a x2 gain on time-to-breakdown at 1GHz against DC TDDB off-state stress. Based on extraction of $\boldsymbol{\mathrm{I}_{\text{Dlin}}}$ degradation, no frequency effect is observed from DC to 1GHz off-state stress conditions. Modeling of on-state and off-state interactions based on sum of degradations modes is then demonstrated and supported by experimental data.
