Abstract
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 0.18â¯Âµm TSMC CMOS technology parameters. The simulation exhibits a tuning range of 432â¯MHz to 3.54â¯GHz, a phase noise in the range of â84â¯dBc/Hz to â104.6â¯dBc/Hz at 1â¯MHz offset from carrier and a figure of merit of 178.4â¯dB in 1.453â¯GHz.
