Abstract
A CMOS temperature sensor is provided. The CMOS temperature sensor, comprises: a bandgap reference circuit outputting a constant bandgap reference voltage regardless of temperature using a first voltage inversely proportional to temperature and a second voltage proportional to temperature and generating a first current proportional to temperature using the second voltage; a reference voltage generator copying the first current and outputting a reference voltage generated using the first voltage and the copied first current; and a temperature information voltage generator copying the first current and outputting a temperature information voltage proportional to temperature.
