Abstract :
In this paper the PTAT (point to absolute temperature) sensor design in CMOS technology is discussed and presented. Two different structures are described. The first one was implemented together with 12-bit ADC into a test chip. Although this sensor has a small linear region, only up to 60 C, it is fully functional and fulfills all requirements. Nevertheless, that was the reason why the new research was established, and a second structure with wide up to 180 °C linear range was developed.
