The main failure mode of electrostatic actuated RF MEMS, the stiction of the bridge due to dielectric charging, is investigated using an appropriate methodology based on the MEMS microwave performances measurement for the failure detection and on the threshold voltages evolution monitoring for the failure analysis. The authors present an advanced… (More)
In this paper, the application of LVCSR (Large Vocabulary Continuous Speech Recognition) technology is investigated for real-time, resource-limited broadcast close captioning. The work focuses on transcribing live broadcast conversation speech to make such programs accessible to deaf viewers. Due to computational limitations, real time factor (RTF) and… (More)
Design and performance of RF-MEMS Phase Shifters in Ka-band are presented. The used Si compatible technology aims to fabricate RF-MEMS devices which are able to handle medium RF-power. Two Phase Shifter versions were designed and compared with respect to capacitance fluctuations.
This paper describes a design methodology specifically developed for RF-MEMS based tuner, which translates into optimal performances in terms of both impedance coverage of the Smith Chart and |Gamma<sub>MAX</sub>| value. The design methodology is moreover associated with an RF-MEMS technology developed for medium power (in the watt range) applications and… (More)
