CMOS TEMPERATURE SENSOR AND TEMPERATURE MEASURING METHOD OF THE SAME

摘要

According to the present invention, it discloses and is used in a kind of CMOS temperature transmitter and temperature-measuring method. It according to the present invention, include: that the first to the 5th MOS transistor is connected in parallel on and is connected to each other in CMOS temperature transmitter; First to fourth bipolar transistor is connected to the first to the 4th MOS transistor; First resistor (R1) is installed on the first MOS transistor and the first bipolar junction transistor; 4th MOS transistor and the 4th bipolar junction transistor are installed between the second impedance (R2); 3rd resistor (R3) is mounted on the 5th MOS transistor and ground; The first to the 5th MOS transistor for applying output valve and grid with operational amplifier passes through the second MOS transistor and the second bipolar transistor by the first MOS transistor and first resistor between first input end, and between the second input terminal of connection. The saving testing cost of effect of the present invention and time, temperature passes through one test of execution at room temperature by measure, without the method for complicated temperature test, by prediction sensor according to the change procedure of temperature coefficient, using test sensor only once room temperature. ;The 2016 of copyright KIPO submissions
