| 摘要 |
The invention relates to an oscillator circuit comprising an LC resonator (1) to which a number of current paths (2, 3, 4) are connected, which are, in turn, connected in parallel to one another and can be individually switched on and off by switches (4). To this end, the attenuation equalization amplifiers (2) are coupled to the oscillating circuit (1) for the attenuation equalization thereof. Said oscillator circuit enables the steepness of the attenuation equalization of the oscillating circuit to be adjusted without shifting the operating point of the amplifiers (2). This, in turn, permits production-associated component tolerances and an amplitude variation caused thereby to be easily compensated for. The invention is suited, for example, for use in voltage-controlled oscillators used for producing phase locked loops in mass production methods. |
