A voltage controlled oscillator includes a variable capacitance circuit having a plurality of variable capacitance elements, each having a capacitance that is a function of a tuning voltage, two or more oscillator core circuits, each operable over a specified frequency band, and inductive elements connected between the variable capacitance circuit and the oscillator core circuits.

Voltage controlled oscillators with wide tuning range and low phase noise

An apparatus includes a substrate, a capacitance die and an exciter die. The capacitance die is generally mounted on the substrate and may be configured to vary a frequency of a signal in an inductor. The exciter die is generally mounted on the substrate and may be configured to excite the signal. A particular one of the capacitance die and the exciter die may be fabricated with a die mask that has a plurality of available designs. The available designs generally customize the particular die to a plurality of configurations respectively. The capacitance die, the exciter die and the inductor may form a voltage-controlled oscillator.

Voltage-controlled oscillator with mask-selectable performance

An apparatus having a substrate, a first die and a second die is disclosed. The substrate may include a circuit having an inductance. The first die may be (i) mounted on the substrate, (ii) connected to the circuit and (iii) configured to control a frequency of an oscillation of a signal in the circuit. The frequency is generally varied by adjusting a voltage in the first die. The second die may be (i) mounted on the substrate, (ii) connected to the circuit and (iii) configured to excite the signal. The apparatus generally forms a voltage-controlled oscillator.

Laminate-based voltage-controlled oscillator

An apparatus having a substrate with an inductor, a first die and a second die is disclosed. The first die may be (i) mounted on the substrate, (ii) configured to vary a frequency of a signal in the inductor, and (iii) fabricated with multiple first masks. The second die may be (i) mounted on the substrate, (ii) configured to excite the signal, and (iii) fabricated with multiple second masks. A particular one of the first masks generally has several designs that customize the first die to several configurations respectively. A particular one of the second masks may have several designs that customize the second die to several configurations respectively. The first die, the second die and the inductor may form a voltage-controlled oscillator. A selected first design and a selected second design generally establish multiple performances of the voltage-controlled oscillator.
