Latest Patents

One of his latest patents is titled "Phase Locked Loop with Bandwidth Control." This invention includes a first loop, a second loop, and a lock detector. The first loop locks a feedback signal having a frequency equal to a fraction of the frequency of an output signal to a reference signal in phase. The first loop has a first bandwidth, while the second loop locks the feedback signal to the reference signal in frequency and has a second bandwidth. Notably, the first bandwidth is higher than the second bandwidth. The lock detector is coupled to the second loop and increases the second bandwidth in response to detecting that the feedback signal is not locked to the reference signal.

Another significant patent is the "Programmable Fine Lock/Unlock Detection Circuit." This integrated circuit includes a feedback-controlled clock generating circuit, such as a DLL, PLL, or other suitable circuit, that provides a feedback reference frequency signal based on a generated output clock signal. The circuit also features a programmable fine lock/unlock detection circuit that includes programmable static phase error sensitivity logic to sense phase error. This logic sets a phase lock sensitivity window used to determine a fine lock/unlock condition of the generated output clock signal.
