摘要： 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.

摘要： Disclosed is a method and apparatus to extend TDC resolution to better than 1 ps without incurring a matching and power penalty. Higher resolution can be achieved by segmenting the resolution between a mismatch free re-circulating time-to-digital converter (RTDC) and a stochastic time-to-digital converter (STDC). The disclosed RTDC replicates the same delay element to eliminate mismatch with the required dynamic range (200 ps for a 5 GHz example) and moderate resolution (3-5 ps typical corresponding to 6-7 bits for the 5 GHz case). While the STDC can achieve a resolution of 50 fs but with a range of only 3-5 ps which also corresponds to approximately 6-7 additional bits by exploiting process variations and mismatch to achieve a very fine resolution with limited dynamic range.

摘要翻译： 公开了一种将TDC分辨率提高到1ps而不引起匹配和功率损失的方法和装置。 可以通过在不匹配的循环时间数字转换器（RTDC）和随机时间 - 数字转换器（STDC）之间分辨分辨率来实现更高的分辨率。 所公开的RTDC复制相同的延迟元件以消除与所需动态范围（对于5GHz示例为200ps）和中等分辨率（3-5ps典型对应于5GHz情况下的6-7位）的失配。 虽然STDC可以实现50 fs的分辨率，但只有3-5 ps的范围，这也通过利用过程变化和失配来对应于大约6-7个附加位，以获得有限动态范围的非常精细的分辨率。
