Smart Temperature Sensor for Thermal Testing of Cell-Based ICs

In this paper we present a simple and efficient built-in temperature sensor for thermal monitoring of standard-cell based VLSI circuits. The proposed smart temperature sensor uses a ring-oscillator composed of complex gates instead of inverters to optimize their linearity. Simulation results from a 0.18$μ$m CMOS technology show that the non-linearity error of the sensor can be reduced when an adequate set of standard logic gates is selected.

A Fast Concurrent Power-Thermal Model for Sub-100nm Digital ICs

As technology scales down, the static power is expected to become a significant fraction of the total power. The exponential dependence of static power with the operating temperature makes the thermal profile estimation of high-performance ICs a key issue to compute the total power dissipated in next-generations. In this paper we present accurate and compact analytical models to estimate the static power dissipation and the temperature of operation of CMOS gates. The models are the fundamentals of a performance estimation tool in which numerical procedures are avoided for any computation to set a faster estimation and optimization. The models developed are compared to measurements and SPICE simulations for a 0.12mm technology showing excellent results.
