This paper presents a novel design procedure based on gm/Id methodology to achieve a trade-off between tuning range, phase noise and output swing of active-inductor-based current-controlled oscillators (CCOs). It is shown that equations for the phase noise and corner frequency of the selected CCO configuration are related to the gm/Id parameters. In accordance with the above relations, the designed CCO is simulated using 0.18 mu m TSMC CMOS technology parameters. The simulation exhibits a tuning range of 432 MHz to 3.54 GHz, a phase noise in the range of -84 dBc/Hz to -104.6 dBc/Hz at 1 MHz offset from carrier and a figure of merit of 178.4 dB in 1.453 GHz.
