The parameters summary of the developed temperature sensor Energy dissipation of sensor Transfer curve of sensor Temperature was set to 0C during the measurement Temperature sensor bare die photograph (0.98x1.62mm) Measured ambient temperature defined by equation above with offset assumed to be 0C. Thermistor pad Vdd Power supply rejection of sensor Cref part 1 CLK input Vss Sensor accuracy evaluation raw data Integrated coaxial for clock Digital converter FDC Integrated coaxial for data Digital outputs Cref part 2 At 0.8V power supply the temperature was set Such that the output fluctuate between 0C and 0.5C While varying the power supply voltage, the ambient Temperature was adjusted to keep the same sensor output. Schematic of experimental setup Tradeoff between state-of-art temperature sensors Accuracy and energy spent per temperature sample Sensor internal circuits Our sensor
