<p>An integrated Voltage controlled oscillator (VCO) includes varactors and fixed capacitors formed in a 'stacked' arrangement. Forming the VCO integrated circuit by 'stacking' fixed capacitors upon underlying varactors frees up semiconductor surface area for use by other circuit components or permits the implementation of a smaller integrated circuit package. 'Stacking' further permits a decrease in parasitic capacitance associated with interconnections between the fixed capacitors and other components of the VCO.</p> |
