A Single-chip Proportional to Absolute Temperature Sensor Using CMOS Technology
Nowadays it is a trend for electronic circuit designers to
integrate all system components on a single-chip. This paper proposed
the design of a single-chip proportional to absolute temperature
(PTAT) sensor including a voltage reference circuit using CEDEC
0.18m CMOS Technology. It is a challenge to design asingle-chip
wide range linear response temperature sensor for many applications.
The channel widths between the compensation transistor and the
reference transistor are critical to design the PTAT temperature sensor
circuit. The designed temperature sensor shows excellent linearity
between -100°C to 200° and the sensitivity is about 0.05mV/°C.
The chip is designed to operate with a single voltage source of 1.6V.
