A low-voltage low-phase-noise 5.5-GHz differential LC voltage-controlled oscillator (VCO) with quadrature outputs for direct and low intermediate frequency conversion is presented. The circuit is fully integrated in IBM's 65-nm radio-frequency complimentary metal-oxide-semiconductor process. Care has to be taken in achieving low phase noise, whereas the VCO core is powered from a low-voltage supply of 650 mV. The VCO incorporates a digitally controlled technique in order for the direct current… CONTINUE READING
