Latest Patents

David E McNeill holds a patent for a "Phase-locked loop circuit with reduced jitter." This improved phase-locked loop circuit features a variable-frequency oscillator that generates a first oscillator signal. It also includes a reference signal source that generates a second oscillator signal, a control block that generates a select signal, and a frequency divider that processes one of the first and second oscillator signals. The frequency divider produces multiple frequency-divided signals and selects one as the output based on the select signal. Additionally, it synchronizes its output signal to the input signal. The circuit incorporates a frequency comparator that compares the output signal of the frequency divider to a derived signal from the oscillator signals, providing feedback to the variable-frequency oscillator. This design effectively limits the number of signal regenerators introduced by the programmable frequency divider, thereby reducing jitter.
