Latest Patents

Gill's notable patent is titled "Reliable clock source having a plurality of redundant oscillators." This invention involves a phase lock loop circuit (PLL) that is integrated into each VLSI chip requiring clock pulses. To enhance reliability, three crystal oscillators are mounted on the printed circuit board (PC) alongside the VLSI chips. The invention includes a circuit that compares oscillator frequencies to identify any discrepancies in operation and accuracy. A gating circuit then selects and passes clock pulses only from the properly functioning crystal oscillator, ensuring optimal performance. Additionally, programmable counters within the PLLs allow for local generation of clock pulses at a frequency that is a ratio of the crystal-generated clock pulses.
