A VCO is to be designed using a 500 pH inductor and a varactor to cover the range of frequencies 2.8 GHz to 3.2 GHz with . What range of capacitance values must cover? Express this range as a percentage of the nominal capacitance at . Assuming that varies linearly with over the range , by what percentage does change going from 2.8 GHz to 3.2 GHz?
