Abstract
This paper presents a low power low voltage temperature sensor designed in a 0.13 μm CMOS technology. The circuit consist of a bandgap voltage reference and a second order sigma-delta modulator. The circuit was designed to operate with a minimum power supply of 0.5 V. The voltage reference circuit operates from -50°C to 110°C with a temperature coefficient of 67.15 (ppm/°C) with a maximum power dissipation of 5.9μW. The bandgap circuit combined with the second order Δ modulator dissipates 6.1μW to 11.7μW over a -30°C to 70°C range.
