Abstract
We describe a dual modulus prescaler that may be used in a high frequency PLL. The prescaler comprises a frequency division unit to generate a prescaled signal by dividing a frequency of an input signal by a division ratio and a frequency division ratio controller to determine the division ratio responsive to a count signal and the prescaled signal. The frequency division unit divides a frequency of an input signal by a division ratio of 2N or (2N−1) to output a prescaled signal. The frequency division ratio controller determines a division ratio responsive to a count signal and the prescaled signal.
