摘要： PROBLEM TO BE SOLVED: To provide a voltage-controlled oscillator of higher integration than those of conventional technology, with the size reduced, without changing inductance of an inductor.
SOLUTION: The voltage-controlled oscillator comprises an oscillating stage, having two coupled CMOS inverters forming a quadrupole with two inputs and two outputs, and two oscillating circuits, placed respectively between the inputs and the outputs of the inverters and each having an inductor. The quadrupole is designed so that the two outputs are in phase. Two inductors of the oscillating circuits are produced by means of MOS technology and are superposed one on top of the other. The region, occupied with the oscillator, can be reduced down to a half maximally, by superposing the two inductors. The oscillator has an amplifying stage, comprising two MOS transistors which are reverse biased to each other. Each gate of the MOS transistors is connected to one of the oscillation stages.

摘要： A novel and useful RF oscillator suitable for use in applications requiring ultra-low voltage and power. The oscillator structure, employing alternating current source transistors, combines the benefits of low supply voltage operation of conventional NMOS cross-coupled oscillators together with high current efficiency of the complementary push-pull oscillators. In addition, the 1/f noise upconversion is also reduced. The oscillator can be incorporated within a wide range of circuit applications, including for example a conventional phase locked loop (PLL), all-digital phase-locked loop (ADPLL), wireline transceiver circuits and mobile devices.
