This work presents a novel frequency planning scheme associated with a reference frequency generation scheme that has the potential of providing low phase noise contribution for several wireless standards including DCS1800, WCDMA II and III, DECT, WLAN a/b/g and Bluetooth. The scheme is particularly useful when implemented in future technologies and can be extended to cover newer wireless standards in newer bands of interest. It uses a single multi-band voltage-controlled oscillator (VCO) with switching inductors and high speed dividers directly generating the quadrature outputs. The VCO itself covers the frequency ranges from 4.8GHz to 6GHz and from 6.8GHz to 8GHz. Its phase noise is ??136dBc/Hz at 1MHz offset from a center frequency of 1.85GHz. The design is sent for fabrication using 0.18??m CMOS
