Latest Patents

Frey's latest patents focus on phase error cancellation in fractional-N phase-locked loops. The first patent describes a method for generating a noise cancellation signal by supplying a divide value to a delta sigma modulator circuit. This process generates a divide control signal that controls the feedback divider in the phase-locked loop. An error term is created to indicate the difference between the generated divide control signal and the supplied divide value. This error term is then integrated to produce an integrated error term, which is utilized to generate the phase error cancellation signal. The second patent further refines this process by quantizing the integrated error term using a second delta sigma modulator, thereby enhancing the cancellation signal's effectiveness.
