Abstract :
A new, computer-assisted method, based on small-signal "S" parameters, is described for the systematic design of wide-band VCO\´s. The method has been applied to design 6-12-GHz and 12-18-GHz GaAs FET VCO\´s, and it has shown an excellent capability to predict the maximum obtainable tuning bandwidth. The tuning linearity of the VCO\´s has also been optimized Delta f/f <= +-0.4 percent over a 3-GHz bandwidth.
