Dynamically adjusting supply voltage based on monitored chip temperature |
摘要 |
In an embodiment, a method includes monitoring a temperature of a semiconductor chip and adjusting a supply voltage to the semiconductor chip based on the monitored temperature. The temperature may be monitored by a temperature sensor located on-chip or off-chip. Adjusting the supply voltage includes increasing the supply voltage as a function of the monitored temperature decreasing. The increase to the supply voltage occurs only if the monitored temperature is below a threshold temperature. The supply voltage adjustment is determined by a linear relationship having a negative slope with temperature. |

1. A method comprising:
monitoring a temperature of a semiconductor chip; adjusting a supply voltage to the semiconductor chip by increasing the supply voltage as a continuous function of the monitored temperature decreasing, wherein adjusting the supply voltage occurs only if the monitored temperature is below a threshold temperature and the supply voltage adjusted is determined based on a linear relationship having a negative slope between the supply voltage and the monitored temperature as defined by the continuous function. |
