Kastratović, Sanja (author)This thesis presents the design of a low-power, sub-1V, BJT-based temperature sensor. It is based on a capacitively-biased (CB) BJT front-end, in which capacitors are discharged across diode-connected BJTs to obtain proportional-to-temperature (PTAT) and complementary-to-temperature (CTAT) voltages. These voltages are then digitised by a...master thesis 2023

van den Berghe, Marjolein (author)Geothermal energy can be promising to help the energy transition. Warm water is pumped up from a geothermal well and after it is cooled down, the cold water is reinjected into the hot aquifer underground. The temperature change could cause chemical balances to be disturbed and result in precipitation on the porous medium of the aquifer. This...bachelor thesis 2023
