A CMOS thermal sensor and its applications in temperature adaptive design

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 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
