Circuit, a time-to-digital converter, an integrated circuit, a transmitter, a receiver and a transceiver

A time-to-digital converter comprising:

• an input signal processing circuit configured to receive at least one input signal and configured to generate a sequence of digital values indicative of time intervals concerning events comprised in the at least one input signal;
• a digital data processing circuit configured to generate a sequence of processed values at a lower frequency than a frequency of the sequence of the digital values, wherein each processed value is based on a plurality of the digital values of the sequence of digital values;
• and
• a noise cancellation circuit coupled to an output of the digital data processing circuit, and configured to compensate a phase shift,
• wherein the noise cancellation circuit outputs a value indicative of the phase shift.

An integrated circuit comprising a circuit, the circuit comprising:

• a controllable oscillator configured to generate an output signal based on a control signal;
• an input signal processing circuit configured to receive a reference signal and to generate a sequence of digital values indicating a phase relation between the reference signal and the output signal or a signal derived from the output signal;
• a digital data processing circuit configured to generate a sequence of processed values at a lower frequency than a frequency of the sequence of the digital values,
• wherein each processed value is based on a plurality of the digital values of the sequence of digital values,
• wherein the control signal is based on the sequence of processed values;
• and
• a noise cancellation circuit coupled between the input signal processing circuit and the controllable oscillator and configured to compensate a phase shift caused by a switching of a frequency divider coupled between the controllable oscillator and the input signal processing circuit,
• wherein the noise cancellation circuit outputs a value indicative of the phase shift.
