The apparatus may include a first oscillator configured to generate a first oscillation signal, a frequency modulator configured to generate a frequency-modulated oscillation signal from the first oscillation signal based on a sequence of control words, a frequency modulation code generator configured to generate a sequence of frequency modulation codes for generating an FMCW waveform, and a frequency multiplier configured to generate the FMCW signal by up-converting the frequency-modulated oscillation signal. The sequence of control words is generated based on the sequence of frequency modulation codes. The apparatus may include a second oscillator configured to generate a second oscillation signal, and a phase detector configured to detect a phase difference between the first oscillation signal and the second oscillation signal and generate an offset code based on the phase difference.

摘要： A re-circulating time-to-digital converter (TDC) can include a triggered reference ring oscillator (TRRO) and a delay module. The triggered reference ring oscillator can, when triggered by a reference signal edge, generate a periodic ring oscillator signal with a ring oscillator period that is a selected ratio of a voltage-controlled oscillator (VCO) period. The delay module can store, in a plurality of latches, samples of a VCO signal clocked by the periodic ring oscillator signal. Each latch can generate an output of the sample, and each latch output can represent a time difference polarity between VCO signal and TRRO signal. In another example, the re-circulating TDC can include the triggered reference ring oscillator, a digital frequency lock module, and a TDC post-process module. The digital frequency lock module can generate a ring oscillator control signal, which sets the ring oscillator period for the triggered reference ring oscillator. The TDC post-process module can generate a TDC output, which can be a binary representation of a phase difference between a reference signal and a VCO signal.
