To meet severe aeronautic environment constraints, we propose in this paper a versatile 794μW autonomous multi-power-source wireless sensor system interfacing with aeronautic-grade resistive bridge transducers and operating over a wide range of −40°C to +180°C in 180nm HT SOI technology. Compared to previously reported works, it provides robust and versatile 8Sps-1kSps sensor interface and RFID/micro...
This paper reports the damping control of a MEMS resonator, vibrating at several kilohertz, using tiny p-doped piezoresistive silicon nanowires (SiNW). Due to thermal piezoresistive back action (TPBA), DC-current biasing of the nanobeams induces a strong increase of the damping rate, about 2 decades above the intrinsic damping rate of the resonator. Intrinsic quality factor (QF) around 3.104 is here...
Silver sintering is a promising emerging microelectronic assembly technology. In this paper sintered silver attachment joints of silicon dies have been studied. It has been pointed out that in pressureless process conditions porosity can disappear of some zones of silver sintered attachment joints. The link between densified zones and the thermo-mechanical stress has been demonstrated. Densified zones...
In this paper, we study the resonance frequency resolution of a MEMS resonator based on suspended piezoresistive silicon nanogauges transduction. Nanowire strain gages are attractive for MEMS resonators thanks to their high sensitivity to motion. They have excellent force sensitivity due to their small cross-section area (250×250nm2) and a negligible footprint. Hence, this transduction mean exhibits...
Resonant structures based on the combination of an electromechanical microresonator made in a thick single crystal Si layer and a differential piezoresistive detection with Si nanowires is a recent concept allowing a breakthrough in downscaling physical resonant sensors with equal to better performances. With an optimized design, the vacuum quality factor of these resonant structures will be ultimately...
A novel coreless technology based on an existing process, initially designed to produce integrated passive components for commercial temperatures, is used and its capability at 200°C is tested. Design aspects and electrical characterizations of the samples are presented. Finally, an endurance test shows a satisfactory behaviour at high temperatures.
