Latest Patents

Drzala holds a patent for a "Digital phase lock loop system." This invention features a macro phase detector that responds to large phase deviations between a locally generated signal and a reference signal. It actuates a successive frequency approximation register to effect major count alterations in a counter, which controls a digital-to-analog converter and, in turn, a voltage-controlled oscillator. The system is designed to detect small phase errors, average them, and use this information to adjust the count in the counter for sensitive frequency adjustments. Additionally, a second counter is clocked by the phase detector at half the rate of the first counter, updating the first counter each time the phase difference reverses polarity. In the event of a loss of reference signal, a detector activates to freeze the count in the counter, maintaining frequency and phase accuracy within the controlled oscillator.
