Abstract | This letter studies and compares class-B VCOs using spiral inductors with the proposed dual-layer patterned floating shield (DL-PFS) and conventional single-layer patterned floating shield (SL-PFS). The proposed DL-PFS technique utilizes two lowest metal layers to effectively reduce the capacitive induced current to the substrate in an on-chip spiral inductor, thereby boosts its Q-factor by 40% when compared with the conventional SL-PFS approach. We fabricated, as a proof of concept, the class-B LC VCOs using the DL-PFS and SL-PFS in 0.13 µm CMOS. Operating at 10 GHz, the VCO with the DL-PFS inductor measures a 3.6 dB phase noise (PN) improvement at the same power consumption of 2.12 mW. Specifically, the VCO with DL-PFS inductor is tunable from 9.3-to-10.1 GHz and measured PN at 10 GHz is −132.5 dBc/Hz at 10 MHz offset while consuming 2.12 mW at the lowest 0.6 V supply. The achieved figure-of-merit (187.4 dBc/Hz@1 MHz offset) compares favorably with the recent state-of-the-art. |
