Active inductor oscillators and noise dynamics

Summary form only given, as follows. The reported oscillator use active inductor topology as a cost-effective alternative to currently available varactor-tuned oscillator (VTO) circuits for the application in third and later generation communication systems. The state-of-the-art technology is analytically validated with CAD-simulated and measured data. It was observed that the classical Leeson phase noise model does not hold good for an active-inductor oscillator; therefore, a unified noise model is needed to explain the discrepancies.
