Abstract
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.
