摘要： A phase detector of a phase-lock-loop circuit measures a phase error between an output signal of an oscillator and a synchronizing signal. When a difference between the phase error that is measured in a pair of horizontal line periods exceeds a first magnitude, that is indicative of phase error inconsistency, the phase of the oscillator output signal is not corrected and the phase-lock-loop circuit operates in an idle mode of operation.

摘要： A variable capacitance circuit comprising a capacitor array, associated switching elements and transient impedance varying circuits. The capacitor array comprises a plurality of capacitor elements connected to a common node coupled to a crystal oscillator in a crystal oscillator portion and each capacitor element includes a connected switching element that controls activation of selected capacitor elements that are selectively placed in operation as load capacitance with the crystal oscillator to change and adjust its frequency. Further, circuits are provided in a temperature compensation portion to selectively control the activation of the switching elements based upon decoded compensating values provided in memory, such as based upon sensed oscillator temperature conditions. The transient impedance varying circuits comprise multi-level voltage generating circuits for changing the continuity impedance of activated switching elements, among switching elements being switched, to another impedance level or one of a plurality of additional impedance levels. As a result, an intermediate impedance value can be created between the ON and OFF states of the switching elements so that there is no rapid change in the total equivalent capacitance imposed by the capacitor array on the oscillator resulting in smooth capacitance switching which corresponds to smoother frequency adjustment of oscillator output.

摘要： The present invention is directed to a distributed dual-band oscillator suitable for low-phase-noise applications. The invention is configured to switch between the odd and even resonant modes of a fourth-order resonator. The switches used for mode selection do not conduct current and therefore do not affect the quality factor (Q) of the resonator. The benefit of this feature is relatively low phase noise.

摘要： An oscillator circuit having a source of an oscillating signal, a tank circuit including an inductor and a capacitor, and a discretely switchable capacitance module configured to control an amount of capacitance in the oscillator circuit. The discretely switchable capacitance module includes, in one embodiment, a capacitor coupled between a first node and a second node, a switch, having a control node, coupled between the second node and a third node; and a DC feed circuit, having a first end coupled to the second node and a second end configured to receive a first or second control signal. The control node of the switch is tied to a predetermined bias voltage. When the first control signal is applied, the capacitor is coupled between the first node and the third node via the switch such that the capacitor is coupled in parallel with the capacitor of the tank circuit, and when the second control signal is applied the capacitor is decoupled from the tank circuit.

摘要： In a high-frequency oscillator, a first resonance circuit and a second resonance circuit are respectively connected to a first amplifier circuit and a second amplifier circuit. A selection circuit includes a first switch circuit and a second switch circuit which selectively operate one of the first amplifier circuit and the second amplifier circuit. A grounded capacitor is connected to output sides of the first amplifier circuit and the second amplifier circuit. The grounded capacitor is commonly used by both the first amplifier circuit and the second amplifier circuit. An auxiliary grounded capacitor is connected between the first switch circuit and the first amplifier circuit. Accordingly, the grounded capacitor and the auxiliary grounded capacitor are connected to each other in parallel only when the first amplifier circuit is activated.
