Latest Patents

Russell W. Brown holds a patent for an "Auto-centered phase-locked loop." This invention is a multi-band processing system designed to automatically tune the oscillator of a phase-locked loop to the frequency and phase of an applied input. The system comprises an error detection circuit, a frequency controller, a scaling circuit, and a phase and frequency controller. The applied input and the oscillator output are coupled to the error detection circuit, which drives a charge pump/filter circuit based on the error output. An error signal is derived from the difference between the loop charge pump output V.sub.1 and a preset charge pump zero error reference signal V.sub.ref. The frequency controller regulates the oscillator output frequency according to a frequency error component of V.sub.1 - V.sub.ref. The scaling circuit adjusts the oscillator output frequency based on a system scaling signal N, while the phase and frequency controller fine-tunes the oscillator output frequency and phase according to V.sub.1 - V.sub.ref when a 1/N multiple of the oscillator output frequency is compared to the applied input frequency.
