摘要： A frequency doubler circuit arrangement comprises a full wave rectifier circuit having an input and a first terminal, the first terminal being connected to a first supply terminal via a first current source, and the input forming an input of the frequency doubler circuit arrangement. A biased transistor circuit is also provided, having a first terminal connected to the first supply terminal via a second current source and being connected to the first terminal of the rectifier circuit. Output terminals of the rectifier circuit and the biased transistor circuit form differential output terminals of the frequency doubler circuit arrangement. The respective outputs of the rectifier circuit and the biased transistor circuit may be connected to a second supply terminal via either an active filter load or a passive filter load, such as an inductance-capacitance-resistance filter. Such a frequency doubler circuit may be employed in a radiotelephone device such that a single voltage controlled oscillator may be utilized to provide signal sources at more than one operating frequency.

摘要： An integrated circuit having a substrate and an LC tank circuit comprises an inductor with parallel capacitors. The capacitors include triple plate integrated capacitors having a highest metal plate, a common middle plate and a lowest metal plate. The lowest plate is connected to a virtual ground node. A control circuit element connected to the middle plate allows the resonant frequency of the tank circuit to be controlled.

摘要： An electrical component structure (14) comprises a plurality of overlying substantially parallel layers (15, 16). Each layer (15, 16) provides a lattice (17, 20) comprising a first set of conductive tracks arranged substantially orthogonal to, and electrically connected with, a second set of conductive tracks. Conductive islands (18, 22) are located in windows of the lattices (17, 20), the conductive islands being electrically isolated from the tracks. The lattice (17, 20) of each layer (15, 16) is electrically connected to the conductive islands (22, 18) of the other adjacent layer (16, 15).

摘要： An amplifier circuit arrangement comprises first and second long-tailed pairs of transistors each including an inductor to provide a constant current source for their respective transistor pair. Each of the transistors of the pairs is provided with a bias current on its base electrode. A differential input signal is applied between the base electrode of one transistor, via a dc blocking capacitor and an input terminal, and the base electrode of another transistor, via a dc blocking capacitor and an another input terminal. The collector electrodes of two of the transistors are connected together and to an output terminal. The collector electrodes of the other two transistors similarly are connected together and to the other output terminal. A differential output signal is provided between the output terminals. This connection of the collectors of the transistors, which can be described as parallel connection, provides summation of the differential signals provided by the transistor pairs.
