Abstract

Temperature sensors and voltage references require cells that generate both PTAT (Proportional To Absolute Temperature) and NTC (Negative Temperature Coefficient) voltages. We present a novel theoretical approach based on a 'quasi-constant' current to obtain these voltages in standard CMOS technology using no resistors. A test circuit was fabricated in a 0.8 : μ m CMOS process. We performed measurements in a 305 K to 375 K temperature range which verify the expected results. The circuit draws under 50 nA from a 1.6 V to 3.0 V supply.

Ultra low-voltage ultra low-power CMOS threshold voltage reference
SBCCI '06: Proceedings of the 19th annual symposium on Integrated circuits and systems design

A simple voltage reference source in weak inversion CMOS for ultra low-voltage and ultra low-power applications is presented. Its voltage reference is provided by the threshold voltage of an nMOS transistor, as it can be verified in the theoretical ...
A 10 b 120 MS/s 108 mW 0.18 μm CMOS ADC with a PVT-insensitive current reference

This paper proposes a 10 b 120 MS/s CMOS ADC with a PVT-insensitive current reference. The designed current reference shows a mean temperature drift of 35.2 ppm/°C in the temperature range from 25 to 100°C and a supply rejection of 1.1%/V between 1.6 ...
A high accuracy CMOS subthreshold voltage reference with offset cancellation and thermal compensation

This paper presents a high accuracy CMOS subthreshold voltage reference without BJTs for the low-supply-voltage and low-power application. The low supply voltage and low power dissipation are achieved, by making MOSFETs work in the subthreshold region. ...
