Abstract

Representative implementations of devices and techniques provide non-linearity detection and mitigation for a phase interpolator of a controlled oscillator circuit, such as a PLL. A bit stream output of a phase detector of the oscillator circuit is segmented according to multiple phase positions of the phase interpolator, forming a bit stream for each of the multiple phase positions. Each bit stream of each phase position is analyzed, and phase position errors may be detected and mitigated based on the contents of the bit streams.
