摘要： A voltage-controlled oscillator device with an LC-resonant circuit, in particular for implementing integrated voltage-controlled oscillators for the lower GHz range, is disclosed. The device achieves continuous frequency tunability in a wide range in particular with a low level of phase noise and phase jitter. In the voltage-controlled oscillator, a second inductor can be periodically switched in parallel and/or in series with at least one first inductor of the LC-resonant circuit by way of a switching means actuated with the oscillator frequency. A control input of the switching means is connected to a variable dc voltage. In that respect the relationship of the duration of the conducting state and the duration of the non-conducting state of the switching means is variable within an oscillation period of the oscillator in dependence on the value of the control voltage. In accordance with the relationship of the duration of the conducting state and the duration of the non-conducting state of the switching means within an oscillation period of the oscillator the time-averaged effective inductance is variable in dependence on the value of the control voltage.

摘要： The invention relates to a voltage-controlled oscillator with an LC resonant circuit, especially for producing integrated voltage-controlled oscillators for the lower GHz range. The aim of the invention is to provide a voltage-controlled oscillator with an LC resonant circuit with which a continuous frequency tuning across a wide range of frequencies can be achieved with only little phase noise or phase jitter. To this end, the voltage-controlled oscillator with an LC resonant circuit with at least one inductivity can be connected to a further inductivity in periodic parallel and/or in series via a switch device that is actuated by the oscillator frequency, one control input of the switch device being connected to a variable DC voltage. The ratio of the duration of the conductive state and the duration of the non-conductive state of the switch devices can be modified within an oscillation period of the oscillator depending on the value of the control voltage. Corresponding to the ratio of the duration of the conductive state and the duration of the non-conductive state of the switch devices within one oscillation period of the oscillator the time-averaged, effective inductivity can be modified depending on the value of the control voltage.

摘要： A ring oscillator is operated from two negatively correlated supply voltages, instead of from the usual one supply voltage. An auxiliary supply voltage VDD2 is generated from the supply VDD by means of an inverting amplifier, such that VDD2 decreases if VDD increases and vice versa, m stages of an n-stage ring oscillator operate from VDD2 and the remaining stages from VDD. This arrangement reduces the oscillator's frequency sensitivity to fluctuations in supply and/or substrate voltage, therefore, the frequency exhibits less jitter due to the noise in these voltages.

摘要： A ring oscillator consisting of a plurality of series connected amplifier stages alternatingly energized by first and second voltages negatively correlated to each other. The output of the final amplifier stage is inverted and connected to the input of the first stage. The second voltage is derived from the first voltage by way of an inverting amplifier which is dimensioned to render the total sensitivity K=df/dVDD zero.
