A programmable semiconductor device has a switch element in an interconnection layer, wherein in at least one of the inside of a via, interconnecting a wire of a first interconnection layer and a wire of a second interconnection layer, a contact part of the via with the wire of the first interconnection layer and a contact part of the via with the wire of the second interconnection layer, there is provided a variable electrical conductivity member, such as a member of an electrolyte material. The via is used as a variable electrical conductivity type switch element or as a variable resistance device having a contact part with the wire of the first interconnection layer as a first terminal and having a contact part with the wire of the second interconnection layer as a second terminal. By varying the electrical conductivity of the switch element, the state of connection of the via with the wire of the first interconnection layer and the state of connection of the via with the wire of the second interconnection layer may be variably set to a shorted state, an open-circuited state or to an intermediate state A two-state switch element includes an ion conductor for conducting metal ions interposed between the first and second electrodes. The second electrode is formed of a material lower in reactivity than the first electrode. The electrical conductivity across the first and second electrodes is changed by the oxidation-reduction reaction of the metal ions. There are provided first and second transistors of opposite polarities, connected to the first electrode, and third and fourth transistors of opposite polarities, connected to the second electrode.

Here disclosed is a parallel-resonance type band-pass filter, which is employed for mobile communications equipment such as a mobile phone. According to the filter, each resonator has a single capacitor and serially connected plural inductors both of which are formed on the surface or on an inner layer of a substrate. Electromagnetic coupling between the resonators is established through electromagnetic coupling between at least a pair of inductors—the inductors of the pair belong to respective resonators. The input and the output terminals are coupled with the respective resonators via the capacitor having a properly determined capacitance. With such a simple structure, the filter also can work as an impedance transformer, with the result that the mobile communications equipment will be much smaller.

Disclosed is a radio frequency filter used for a mobile communication apparatus such as a mobile phone, having an inductor component, a capacitor component, and a resistor component formed of a conductor pattern. The filter includes the conductor pattern formed on the surface of dielectric layer, and an adjusting layer for adjusting the frequency characteristic of the filter formed so as to cover at least a part of the conductor pattern. In the radio frequency filter, the conductor pattern is formed and sintered, followed by adjusting the frequency characteristic of the filter. Accordingly, in the radio frequency filter, the yield of the manufacture is improved. Further, the electrode layer can be single-layered by using extra-thin lines for the conductor pattern and interdigital electrodes for the capacitor. As a result, it is possible to make the filter smaller and thinner by using intaglio-printing technique and thin-film forming technique.

A voltage controlled oscillator comprises an oscillator connected between a power supply line and a low potential power supply voltage and having an output node for outputting an oscillation signal having a frequency changed in accordance with a voltage difference between the power supply line and the low potential power supply voltage. An nMOS transistor is connected at its drain to a high low potential power supply voltage and at its source connected to the power supply line of the oscillator. A gate electrode of the nMOS transistor is connected to receive a control signal so that a source voltage of the nMOS transistor is determined by a voltage of the control signal and is supplied to the power supply line of the oscillator, with the result that the oscillation frequency of the oscillator is controlled by the voltage of the control signal. A level converter is connected between the high potential power supply voltage and the low potential power supply voltage and has an input node connected to the output node of the oscillator and an output terminal for outputting an output signal. The level converter converts an amplitude of the oscillation signal to an amplitude of the output signal corresponding to a voltage difference between the high and low potential power supply voltages. Thus, a voltage controlled oscillator having an excellent insensibility to a power supply voltage variation can be realized.

A voltage controlled oscillator includes a first converter, a second converter and an oscillator. The first converter outputs a first current proportional to an input voltage. In this case, an increase rate of the first current is decreased as the input voltage is increased. The second converter outputs a second current proportional to the input voltage. An increase rate of the second current is increased as the input voltage is increased. The oscillator outputs an oscillation signal in response to a summation of the first current and the second current.
