摘要： An RC filter is calibrated to a desired cutoff frequency by initializing the filter with a cutoff frequency. An input signal is filtered by the RC filter to provide a filter output signal having phase and frequency values. The cutoff frequency of the RC filter is adjusted based on the phase and frequency values of the filter output signal if the phase and frequency values do not satisfy a predetermined condition. The filtering and adjusting are repeated until the phase and frequency values of the filter output signal satisfy the predetermined condition. A calibration apparatus has a frequency generator, a resistor-capacitor (RC) filter, a phase comparator, a frequency detector, and a state machine. The phase comparator, frequency detector, and state machine are configured to calibrate the RC filter to a cutoff frequency specified by the reference signal based on a filter output signal of the RC filter.

摘要： Methods and apparatuses for time to digital conversion (TDC) are disclosed. A timing circuit comprises a TDC circuit, a calibration module, and a correction module. The TDC circuit is configured to provide a timing signal indicative of a timing difference between edges of a periodic reference clock signal and a variable feedback signal. The TDC circuit is also configured to provide a delay signal that is variably delayed relative to the reference clock signal. The calibration module is configured to provide a calibration signal to increase and decrease a total delay of the TDC circuit based on a time delay of the calibration signal plus a time delay of a correction signal. The correction module, which is configured to receive the timing signal and provide the correction signal, minimizes harmonic spurs in a frequency response of the timing signal by operating at a frequency of the reference clock signal.
