Abstract
A novel built-in CMOS temperature sensor is designed.Threshold voltage can be changed into digital-output thiough utilizing the variety between the threshold voltage of a MOS transistor and carrier mobility vs temperature.The Circuit is simple and can turn on by self.The simulation result by Spectre shows the circuit has many advantages
such as good linearity
higher sensitivity and integration with SOC on one chip.
