Abstract

With transistor feature size scaling and higher integration density, power density has become a major problem. High power density results in elevated on chip temperature, which has significant impacts on power consumption and circuit reliability. In this work, we have presented a temperature adaptive design technique using a novel low overhead CMOS temperature sensor. We have shown that, by online monitoring of temperature, circuit power consumption can be adjusted adaptively so as to stabilize the chip temperature and achieve a robust design.
