摘要： The invention relates in general to frequency synthesis and in particular to an oscillator for use in generating a signal having a desired frequency. An oscillator for use in generating a signal having a desired frequency in a frequency synthesizer is thus provided. The oscillator comprises: a first inductor element being electrically coupled from one end of a first capacitive element to a first voltage connection point; a second inductor element being electrically coupled from one end of a second capacitive element to a second voltage connection point; a third inductor element being electrically coupled from the other end of the first capacitive element to the first voltage connection point; a fourth inductor element being electrically coupled from the other end of the second capacitive element to the second voltage connection point; said inductor elements being arranged such that a conductive trace loop formed by the first and third inductor elements is interleaved with a conductive trace loop formed by the second and fourth inductor elements such that said conductive trace loops are configured to operate in substantially the same magnetic field, wherein a first drive circuit is electrically coupled to the first and second inductor element forming a first resonance circuit with the first and second capacitive elements and a second drive circuit is electrically coupled to the third and fourth inductor element forming a second resonance circuit with the first and second capacitive elements, such that the first and second drive circuits are mutually configured to establish and maintain a unified oscillation in the first and second resonance circuits at the desired frequency.

摘要： The disclosure relates to an oscillator for use in generating frequencies in a frequency synthesizer, comprising: a first inductor element forming a metal trace loop with at least one turn, and a first capacitive circuit arranged to form a first resonance circuit with the first inductor element and being connected to the first inductor element through at least one first connection terminal, wherein the first capacitive circuit comprises at least one capacitive element and an electrical components arrangement arranged to establish and maintain an oscillation. The oscillator is characterized in that a second capacitive circuit comprising at least one capacitive element and an arrangement of electrical components, is arranged to form a second resonance circuit with the first inductor element and being connected to the first inductor element through at least one second connection terminal located on the opposite side of the first inductor element in respect to the first connection terminal of the first capacitive circuit, wherein the first and second resonance circuits are tuned to substantially the same frequency. The invention also relates to a frequency synthesizer and to a network node for use in a telecommunications network.

摘要： The invention relates to a high-speed non-integer frequency divider circuit for use in generating frequencies in a communication device, comprising: at least four bi-stable memory devices each having an input terminal, a clock terminal and an output terminal for outputting an output signal. The high-speed non-integer frequency divider circuit is characterized in that the at least four bi-stable memory devices are arranged in a cascaded chain such that each bi-stable memory device following the first bi-stable memory device receives the output signal of a previous bi-stable memory device in the cascaded chain at its input terminal and such that at least one of the output signals of the last bi-stable memory device is used to control the input terminal of the first bi-stable memory device, and in that the frequency divider circuit further comprises a clocking arrangement adapted to provide an in-phase clock signal, a quadrature clock signal, an inverse of the in-phase clock signal and an inverse of the quadrature clock signal to the clock terminals of each of the at least four bi-stable memory devices such that a combination of output signals from the at least bi-stable memory devices produces a frequency divided output signal of the frequency divider circuit having a frequency division ratio of fourths of the frequency of the in-phase clock signal. The invention also relates to a frequency synthesizer and a communication device.
