Title: -55°C to 170°C high linear voltage references circuitry in 0.18ìm CMOS technology
Author: Tzuo-sheng Tsai, J.; Chiueh, H.
Abstract: High linear voltage references circuitry are designed and implemented in TSMC 0.18µm CMOS technology. Previous research has proposed the use of MOS transistors operating in the weak inversion region to replace the bipolar devices in conventional PTAT(proportional to absolute temperature) circuits. However such solutions often have linearity problem in high temperature region due to the current leaking devices in modern deep sub micron and nano-scale CMOS technology. The proposed circuit utilized temperature complementation technique on two voltage references, PTAT and IOAT (independent of absolute temperature) references, to enhance the linearity and produce a more stable IOAT voltage reference. Base on the simulation results, the R-squares of both circuitries are better than 0.999 in a considerable wider temperature range from - 55°C to 170°C. Thus, a fully integrated temperature sensor with wider temperature range is designed and easily to integrate to modern system-on-chip designs with minimal efforts.
