Abstract: Methods and digital circuits provide frequency correction to frequency synthesizers. Dual switched-capacitor voltage detectors connected to an input signal periodically sample the voltage of the input signal, and then determine a fundamental frequency of the input signal from the output of the dual switched-capacitor voltage detectors. The sample period of the dual switched-capacitor voltage detectors is proportional to a time period between a previous pair of voltage peaks detected in the input signal, thereby eliminating harmonic components in the original signal which might otherwise cause errors in frequency estimation without causing unwanted sluggishness in the transient response of the frequency detection process. The time period between the previous pair of detected voltage peaks is used to create a decay signal that initiates a capacitor decay time for each voltage detector.
