  • Abstract
    RF-stress effects on MOS power-amplifier performance are studied. The class-E power-amplifier power efficiency as a function of breakdown (BD) location has been evaluated. The power efficiency degrades with gate-oxide RF stress due to increased gate leakage current and reduced output voltage. The degradation is enhanced when the BD location is closer to the drain side than the source side.
