Abstract: An integrated, tunable inductance network features a number of fixed inductors fabricated on a common substrate along with a switching network made up of a number of micro-electromechanical (MEM) switches. The switches selectably interconnect the inductors to form an inductance network having a particular inductance value, which can be set with a high degree of precision when the inductors are configured appropriately. The preferred MEM switches introduce a very small amount of resistance, and the inductance network can thus have a high Q. The MEM switches and inductors can be integrated using common processing steps, reducing parasitic capacitance problems associated with wire bonds and prior art switches, increasing reliability, and reducing the space, weight and power requirements of prior art designs. The precisely tunable high-Q inductance network has wide applicability, such as in a resonant circuit which provides a narrow bandwidth frequency response which peaks at a specific predetermined frequency, making possible a highly selective performance low noise amplifier (LNA), or in an oscillator circuit so that a precise frequency of oscillation can be generated and changed as needed.

Abstract: A voltage controlled oscillator provides a fixed amplitude output at an adjustable frequency. The voltage controlled oscillator includes a first transistor including an emitter, a base, and a collector. A first capacitor is connected between the emitter and the base of the first transistor. An inductance simulating device generates a controllable impedance and includes second and third transistors each with a base, an emitter, and a collector. The second and third transistors are connected between the base and the collector of the first transistor. The controllable impedance includes an inductive reactance component related to a quiescent bias current flowing through the third transistor. A current source connected to the third transistor generates the quiescent bias current to vary the inductive reactance component. The inductive reactance component and the first capacitor vary the adjustable frequency of oscillation.
