Latest Patents

Flanagan's latest patents include innovative methods and apparatuses that enhance the functionality of delay-locked loops. One of his patents is titled "Delay-locked loop with built-in self-test of phase margin." This invention provides a method for measuring the phase margin of a delay-locked loop (DLL) by applying a reference clock to the DLL's reference input. An auxiliary variable delay is incorporated within the DLL, which is adjusted until the DLL becomes unstable. The output generated indicates the phase margin based on the variable delay value at which instability occurs.

Another significant patent is the "System for measuring phase error between two clocks by using a plurality of phase latches with different respective delays." This patent describes a phase error measurement circuit designed for integrated circuits. It includes first and second clock signal inputs, a phase lead detector, a phase lag detector, and a phase error measurement output. The phase lead detector utilizes a phase lead latch, while the phase lag detector employs a phase lag latch, both of which contribute to the final phase error measurement output.
