2. 1. SiC Readout IC for High Temperature Seismic Sensor System

   Author : Ye Tian; Carl-Mikael Zetterling; Ana Rusu; Philip A. Mawby; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide SiC ; bipolar junction transistor BJT ; integrated circuit IC ; sigma-delta Σ∆ ; data conversion; operational amplifier OpAmp ; VBIC; SPICE Gummel-poon; high-temperature; electromechanical; accelerometer; capacitive sensor; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Over the last decade, electronics operating at high temperatures have been increasingly demanded to support in situ sensing applications such as automotive, deep-well drilling and aerospace. However, few of these applications have requirements above 460 °C, as the surface temperature of Venus, which is a specific target for the seismic sensing application in this thesis. READ MORE
