Techniques are provided for compensating for variations in capacitance of capacitors used in resonant circuits, particularly varactors used in voltage-controlled oscillators. Indications of actual varactor capacitances are used to determine which of several inductances to use in the resonant circuit with the varactor. The inductances may be composed of a bondwire inductance, and may also be composed of one or more coil inductors. Based on the determined capacitance indication, a bondwire is connected from a common bondpad to a selected bondpad to complete the resonant tank circuit such that an LC product of the tank circuit is within a desired or acceptable LC product range. |
