In the thesis we can read things regarding temperature, oscillator, voltage, sensor, and consumption. Lots of info related to timer, measurement results, simulation, measurement, and diagram are described in this thesis.
This thesis tells the reader discussion related to frequency, circuits, the temperature sensor, circuit, and simulation results. The following are taken from this thesis:

Furthermore, this thesis presents more things like monitoring system, system, power consumption, temperature sensor, and samples.
