Abstract

A novel tuning mechanism to greatly widen the frequency tuning range of VCO is presented. A tuning range of over 50% has been achieved for a CMOS VCO with the adoption of this technique. Moreover, a constant amplitude control loop is also incorporated in this circuit, ensuring stable oscillation amplitude over the whole tuning range.
