Abstract: A radar monolithic microwave integrated circuit (MMIC) includes a trigger encoder configured to receive a clock signal comprising a plurality of clock pulses having a fixed amplitude and a trigger signal configured to indicate trigger events. The trigger encoder is configured to encode the trigger signal into the clock signal to generate a distributed clock signal by skipping at least one clock pulse of the plurality of clock pulses to indicate a trigger event. The radar MMIC is configured to output the distributed clock signal having the at least one clock pulse skipped to indicate the trigger event. The radar MMIC is configured to receive the distributed clock signal as a received distributed clock signal. The radar MMIC further includes a radar operation controller configured to detect the trigger event based on the received distributed clock signal and initiate a radar operation based on detecting the trigger event.

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.
