Abstract:
A voltage-controlled oscillator (VCO) comprising:an input configured to receive a tuning voltage; a capacitive element coupled to the input and having an actual capacitance C; a first connection point; a plurality of second connection points for coupling to the first connection point, at least one of the plurality of connection points being coupled to the first connection point by a bondwire of a length selected to provide a compensating inductance, at least the compensating inductance and the capacitive element being coupled to form a tank, the compensating inductance compensating for a deviation in the actual capacitance C from a desired capacitance of the capacitive element and affecting a total inductance L, that includes at least the compensating inductance, such that an LC product of the inductance L and the capacitance C is within a desired range of LC product values; and an output coupled to the tank and configured to carry an output signal having a frequency associated with the LC product.
