Abstract :
The EMI/EMC problems appear in mixed-signal ICs with the increasing frequency and decreasing process geometries. In this paper, the amplitude modulation (AM) is taken into account the LC-VCO based on the TSMC 0.25 um mixed-signal process, and a cascade amplifier circuit, which is not complex, is proposed to optimize the LC-VCO through analyzing the noise coupling transition function of the LC-VCO. Lastly, the efficiency and usefulness of the proposed method is proved in the simulations.
