フィードバックループにおける位相補正を備えた位相ロックドループ

摘要

A frequency synthesizer circuit is disclosed. The frequency synthesizer circuit includes a comparator circuit coupled to a reference clock and a phase-corrected output signal. The frequency synthesizer circuit also includes a loop filter coupled to the comparator circuit. The frequency synthesizer circuit also includes an oscillator coupled to the loop filter. The frequency synthesizer circuit also includes a fractional divider coupled to an output of the oscillator. The frequency synthesizer circuit also includes phase correction circuitry that corrects a phase of an output of the fractional divider to produce the phase-corrected output signal.
