Abstract: abstract:A new PMOS backgate quadrature voltage controlled oscillator (QVCO) is designed and implemented using TSMC 0.18 lm 1P6M CMOS technology. The phase noise of the PMOS back-gate coupled QVCO operating at 1.5 V is measured to be 100 dBc/Hz and 125.08 dBc/Hz at 100 KHz and 1 MHz offset, respectively, for a low power consumption of 15 mW. The backgate QVCO demonstrates a wide frequency tuning range, a low phase noise, and a low power consumption. The corresponding figure-of-merit of the QVCO is 186 dBc/Hz.
