Abstract
A circuit is configured to reduce a noise component of a measured phase signal. The circuit includes an input for a phase signal of an oscillator and an error signal estimator configured to determine parity information and an estimated error amplitude in the phase signal based on the parity information. The circuit further includes a combiner configured to provide the measured phase signal with the reduced noise component based on a combination of the phase signal and the estimated error amplitude.
Claims22
A circuit to reduce a noise component of a measured phase signal, the circuit comprising:
- an input for a phase signal of an oscillator;
- an error signal estimator configured to determine parity information and an estimated error amplitude in the phase signal based on the parity information wherein the error signal estimator is configured to determine the parity information as information on whether the phase signal is in an even or an odd cycle;
- and
- a combiner configured to provide the measured phase signal with the reduced noise component based on a combination of the phase signal and the estimated error amplitude.
A method for reducing a noise component of a measured phase signal, the method comprising:
- inputting a phase signal of an oscillator;
- determining parity information;
- determining an estimated error amplitude in the phase signal based on the parity information wherein the parity information is information on whether the phase signal is in an even or an odd cycle;
- and
- combining the phase signal and the estimated error amplitude to provide the measured phase signal with the reduced noise component.
A non-transitory machine readable storage medium including program code, when executed, to cause a machine to perform a method for reducing a noise component of a measured phase signal, the method comprising:
- inputting a phase signal of an oscillator;
- determining parity information;
- determining an estimated error amplitude in the phase signal based on the parity information wherein the parity information is information on whether the phase signal is in an even or an odd cycle;
- and
