A New Type of CMOS Temperature Sensor
-
Abstract
Theory and design of compatible wide range smart temperature sensors in standard CMOS technology is presented.The simulated temperature sensitivity using a CSMC 06μm mixed-signal CMOS process is –1.15μA/℃ (over the temperature range of -40～125℃) and the measured is –0.99μA/℃.The power dissipation of the sensor is 1.5mW at a 5V voltage supply,and the chip area is 0.025mm2.The characteristics of this sensor make it especially suitable for low-cost high-volume integrated microsystems over a wide range of fields,such as automotive,oil prospecting,biomedical,and consumer. -
