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