The increasing significance of thermal issues in modern VLSI motivates the need for a large number of lightweight, robust and power efficient thermal sensors for accurate thermal mapping and management. We propose use of differential ring oscillators (DRO) for thermal sensing, utilizing the temperature dependence of the oscillation frequency. In current starved inverter topology using the 45 nm technology node, they have a resolution of 2degC and a low active power consumption of less than 25… CONTINUE READING
