Abstract
A frequency adjusting device includes a voltage droop detector and a frequency divider. The voltage droop detector compares a supply voltage with a lower threshold voltage to output a comparison result. When the supply voltage is greater than the threshold voltage, the frequency divider outputs a result of dividing a basic clock signal by a first value as a clock signal. When the supply voltage is smaller than the threshold voltage, the frequency divider outputs a result of dividing the basic clock signal by a second value as the clock signal.
