    Abstract: Determination of digital compensation to compensate for non-linearity of stochastic system configured to sample a phase difference, based on statistical analysis of calibration data generated by the stochastic system in response to a linear phase ramp. The stochastic system may include a set of stochastic sampler circuits to sample a phase difference at periodic events, and calibration data may include a digital value of set of stochastic samples for each of multiple events. The calibration data may include sequences of the digital values in which the digital values increment over a range of the stochastic system (i.e., between saturation states of the stochastic system). Statistical analysis may include histogram analysis to estimate the probability distribution of the calibration data. The stochastic system may be configured as part of a time-to-digital converter, which may be configured within a feedback loop of a digitally controllable phase lock loop.

    Abstract translation: 基于随机系统响应于线性相位斜坡生成的校准数据的统计分析，确定数字补偿以补偿配置为采样相位差的随机系统的非线性。 随机系统可以包括一组随机采样器电路，以在周期性事件中采样相位差，并且校准数据可以包括多个事件中的每一个的随机样本集合的数字值。 校准数据可以包括数字值的序列，其中数字值在随机系统的范围（即，随机系统的饱和状态之间）增加。 统计分析可以包括直方图分析来估计校准数据的概率分布。 随机系统可以被配置为时间 - 数字转换器的一部分，其可以配置在数字可控锁相环的反馈回路内。

    Abstract: An apparatus for generating a frequency estimate of an output signal includes a reference signal generator configured to generate a reference clock signal. The apparatus includes frequency estimation circuitry configured to generate a cycle count based frequency estimation of the output signal based on the reference clock signal and a clock cycle count of the output signal. The frequency estimation circuitry further generates a fractional frequency estimation of the output signal based on the reference clock signal and a plurality of time-to-digital conversion phase samples of the output signal. The frequency estimation circuitry further generates the frequency estimate of the output signal using the cycle count based frequency estimation within a range and a frequency error determined from the fractional frequency estimation. The plurality of time-to-digital conversion phase samples and the cycle count based frequency estimation use a same number of reference clock cycles of the reference clock signal.
