A high‐performance quadrature voltage‐controlled oscillator (QVCO) with ring inductor is studied. The QVCO uses a closed‐loop ring inductor and is composed of two complementary negative transconductance cells to replenish the energy loss due to the resistive LC resonator and is implemented in a standard TSMC 90 nm 1P9M CMOS technology. This QVCO operates between 7.05 and 8.15 GHz. The measured phase noise of the VCO operating at 8.15 GHz is −119.98 dBc/Hz at 1‐MHz offset while the QVCO draws 4.2 mA and 3.57 mW consumption from a supply voltage of 0.85 V. © 2012 Wiley Periodicals, Inc.
