The adaptive voltage modulation circuit keeps a count of the number of clock signal cycles during which the supply voltage -. is below the droop threshold voltage. The adaptive voltage modulation circuit increases the supply voltage in response to the count IN exceeding an upper threshold value, and decreases the supply voltage in response to the count being less than a lower threshold value at 1-1 © an end of a defined period.
