摘要： A cyclical pulsing oscillator having a pulse repetition rate close to a crystal resonant frequency in an oscillator provides more useful start-up energy to the crystal oscillator circuit and thus provides much faster start-up time. The start-up pulsing oscillator runs for a number of cycles or until the crystal oscillator amplitude as built up to a desired value. The pulsing oscillator may have a repetition rate of from about one-third to about one-half the crystal resonant frequency, thus providing more useful start-up energy to the crystal oscillator circuit.

摘要： A crystal oscillator circuit comprises a crystal (X 1 ); oscillator circuitry (31) for generating a crystal oscillation signal at an oscillation frequency; and a kick-start circuit (12) for injecting pulses into the crystal during a start-up period. The oscillator circuitry (31) comprises a differential pair of transistors (M 1 , M 2 ) and can operate in an oscillating mode or a start-up mode. In the oscillating mode, the differential pair of transistors are cross-coupled so that a gate terminal of one transistor (M- 1 ) is coupled to a drain terminal of the other transistor (M 2 ), and vice versa, and the drain terminals are coupled to the crystal (X- 1 ) to generate the crystal oscillation signal. In the start-up mode, the kick-start circuit (12) drives the gate terminals of the transistors (M- 1 , M 2 ) with said pulses. This crystal oscillator circuit has a decreased start-up time compared to prior art solutions and a reduced influence of parasitic oscillations.

摘要： L'invention concerne les générateurs d'impulsions à très large bande pour la communication radio en modulation de phase à des fréquences de plusieurs gigahertz. Le générateur comprend un oscillateur formé par une paire de branches différentielles croisées (T1, Τ'1) ayant deux sorties (S, S') reliées à une charge résonante LC. L'émission d'une impulsion UWB est provoquée par l'application d'un courant d'alimentation pendant quelques nanosecondes à la paire différentielle. Deux branches d'injection de courant sont reliées respectivement aux sorties S et S'. La commande de modulation de phase consiste à appliquer un courant d'injection (-Id) à une seule branche pour déséquilibrer la paire différentielle au début de la production de l'impulsion UWB. Selon le côté où est appliqué le courant d'injection, l'oscillation à la fréquence porteuse démarrera avec une phase ou une phase opposée.

摘要： A crystal oscillator is started in a high power mode for a certain period of time to ensure starting oscillation with average grade crystals, then once the certain time period is over the oscillator switches into a low power mode and sustains oscillation with energy pulses triggered by and synchronized with the oscillator output frequency. These energy pulses may be generated on the positive, negative or both positive and negative edges of the clock output waveform.

摘要： The disclosed embodiments provide a system which starts up and shuts down a resonant oscillator circuit. During the start up process, a driving circuit uses a first clock signal to control a first phase output of the resonant oscillator circuit. At the same time, the driving circuit uses a second clock signal to control a second phase output of the resonant oscillator circuit, wherein the first and second clock signals have opposite phases. While the first and second phase outputs are being controlled, the system ramps up an input voltage, which is used to power the resonant oscillator circuit, wherein the ramping takes place across multiple initial oscillation periods. During the shut down process, the system shuts down the resonant oscillator circuit by ramping down the input voltage. After the input voltage has been ramped down, the system clamps the first and second phase outputs to a fixed voltage.

摘要： In a controlled oscillator having a resonator (2) and at least one amplifier (1) with positive feedback, the oscillation signal, which is present at the resonator (2), is fed to an analogue-to-digital converter (21). The analogue-to-digital converter (21) supplies numerical information on the amplitude and/or the phase of the oscillation signal to a control circuit (22). The control circuit (22) emits at least one control signal for setting the phase and/or the amplitude of the oscillation of the oscillator. For producing the control signal the control circuit (22) may be associated with a table of parameters (24). The output of the control circuit (22) is formed by a digital-to-analogue converter (23). In one embodiment, the oscillator is a push-pull oscillator having two transistors (34) as amplifiers, which are connected to a controllable current source (7). The control circuit (22) in this case controls the operating points of the amplifiers (34) via a bias at the base connections of the transistors (34) and via the current through the controllable current source (7). In order to start the oscillator, the base potentials of the transistors (34) are set such that they are asymmetrical.
