Method and apparatus for generating a digital signal of tunable frequency and frequency synthesizer employing same

A method for generating a digital signal of tunable frequency may include generating a periodic first analog signal, determining a sign of a first difference between a value of the first analog signal and a first control value to determine sign flips, wherein the first control value is a variable va...

Beschreibung
Zusammenfassung:	A method for generating a digital signal of tunable frequency may include generating a periodic first analog signal, determining a sign of a first difference between a value of the first analog signal and a first control value to determine sign flips, wherein the first control value is a variable value, and generating the digital signal of tunable frequency on the basis of the determined sign of the first difference, wherein the digital signal of tunable frequency is generated such that a subset of switches of the signal level are coincident with a respective sign flip of the determined sign of the first difference.
