Using the transformer coupling technique, this letter presents a new quadrature voltage-controlled oscillator (QVCO) with bottom series-coupled transistors. The proposed CMOS QVCO has been implemented with the TSMC 0.13 mum 1P8M CMOS process, and the die area is 1.03 times 0.914 mm2. At the supply voltage of 1.0 V, the total power consumption is 3.56 mW. The free-running frequency of the QVCO is tunable from 5.43 GHz to 5.92 GHz as the tuning voltage is varied from 0.0 V to 1.0 V. The measured phase noise at 1 MHz frequency offset is -117.98 dBc/Hz at the oscillation frequency of 5.5 GHz and the figure of merit (FOM) of the proposed QVCO is -187.27 dBc/Hz.
