    摘要： An integrated microwave oscillator as which the generated frequency is stabilized by a dielectric resonator with high quality factor and stability. The positive feedback is assured not only by the dielectric resonator coupled to a line connected to a terminal of the active device, but also by a microstrip resonator connected in parallel to a second line connected to a second terminal of the active device. The signal generated is extracted from the third terminal of the active device.

    摘要： Oscillator circuit comprising an amplifier arrangement being connected to a reference level an output and an input thereof being coupled via a single signal-carrying terminal to a resonant network which is connected to the same reference level as the amplifier arrangement, the resonant network comprising a crystal resonator. A stable oscillation at a higher order crystal resonant frequency is provided by means of an LC-network which selects said higher order crystal resonant frequency and a resistor connected in parallel across the crystal resonator, which prevents parasitic oscillations at the resonant frequency determined by the components of the LC-network and the case or holder capacitance of the crystal resonator.

    摘要： Apparatus and methods are also disclosed related to an oscillator that includes a switching network configured to tune a resonant frequency of a resonant circuit. One such apparatus includes a switching network having a circuit element, such as a capacitor, that can be selectively coupled to the resonant circuit by a switch, such as a field effect transistor. For instance, the switch can electrically couple to circuit element to the resonant circuit when on and not electrically couple the circuit element to the resonant circuit when off. An active circuit can assert a high impedance on an intermediate node between the switch and the circuit element when the switch is off.

    摘要： An oscillator in an integrated circuit in which the oscillator signal is taken from the output of a comparator, and the decision level of the comparator is determined by the voltage difference between the input of the comparator and the substrate of the integrated circuit. Interference voltages on the substrate, caused by other circuitry on the integrated circuit, are compensated with equal interference voltages at the input of the comparator. To effect this compensation, a capacitor is connected between the input of the comparator and the substrate, in lieu of the conventional capacitor that is connected between the input of the comparator and a ground potential.
