Zusammenfassung:Systems, methods and circuitry useful for adjusting a periodic signal such as with a voltage controlled oscillator or a delay line. In one series of embodiments, circuits and methods are provided for controlling current flow through first and second parallel paths where an impedance device in one path emulates the impedance characteristics of a different device in the other path. A phase or frequency characteristic of the periodic signal may be adjusted by alternate switching of current through the two paths.
