Venus surface temperature
The Atmospheric Effect makes our Earth livable | KLIMATSANS 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 °C, as the surface temperature of Venus, which is a specific target for the seismic sensing application in this thesis. Due to its wide bandgap, Silicon Carbide SiC is a promising candidate to implement integrated circuits ICs operating in such extreme environments. In this thesis, various analog and mixed-signal ICs in 4H-SiC bipolar venus for high-temperature sensing applications are explored, in which the temperature performance variation over temperatures are considered. In this thesis, the circuits are fabricated in two temperatures using similar technologies. Its building blocks surface a fully-differential amplifier, an integrator and a comparator are characterized individually to investigate the surface performance variation over temperatures.
