Latest Patents

Roger V Brunt holds a patent for a "Stabilized Phase Locked Loop." This invention features a dual loop phase locked loop system that includes a secondary loop designed to control various circuit, environmental, and process variations. The secondary loop consists of a phase comparator, a filter, a transconductance amplifier, and a one-shot. The output of the one-shot is fed back as an input signal for comparison with a reference signal at the input of the phase comparator. The filter generates a correction voltage based on the phase difference determined by the phase comparator. The transconductance amplifier produces a charging current corresponding to the error voltage from the filter, which controls the charging of the input capacitor to the one-shot circuit. This design ensures inherent stability due to the presence of only one pole near the origin of the S-Plane. The primary loop, which includes a phase comparator, a filter, a transconductance amplifier, and an output means, provides the actual phase locked loop of an input reference signal while deriving compensating analog trim information from the secondary loop. The dynamic characteristics of the primary loop are established by the reference loop, based on the reference clock frequency, and the loop response is controlled by the reference frequency, making it immune to process, temperature, and voltage variations.
