Abstract
This thesis reports on the implementation of a temperature sensor utilizing dual oscillator
temperature measurement principles. Integrated Circuit temperature sensors have been widely
used in applications of circuit boards and CPUs in computer and mobile devices. The old design
using band-gap temperature sensing topology suffers from the large area and the high
complexity of the circuit. Our circuit implementation is inspired by the dual oscillator
measurement principle, which is utilized in the application of frequency meter, etc.
Implementing this circuit using Verilog-AMS, we prove that this approach can be used to build
an IC temperature sensor with high-temperature resolution. Theories and calculations are
included, and further improvements are discussed in detail.
