Abstract
This paper presents a digital frequency multiplier having many features not yet found together in existing multipliers. Its acquisition time is within one period of the input signal and it can follow the input frequency over more than three decades. The relative frequency error on its synchronized output signal is independent of the multiplication factor N and is noncumulative. The maximum value of this error is given by fin/fc where fin is the input frequency and fc a master clock frequency. This represents a decrease in the error value by a factor N over many existing digital frequency multipliers.Keywords
