Abstract—We present an integrated frequency synthesizer
which is able to provide in-phase/quadrature phase signal over
the frequency bands 0.6–4.6 GHz, 5–7 GHz, 10–14 GHz, and
in-phase signal over 20–28 GHz for software-defined radio appli-
cations. An integrated voltage-controlled oscillator (VCO) with
34% tuning range and a set of high-speed dividers are used to
accomplish all the frequencies. To achieve a wide tuning range
