摘要：本申请实施例公开了一种双模振荡器及多相位振荡器。该双模振荡器通过模式切换电路实现两个工作模式之间的切换，可以得到两个不同频段的振荡信号，同时，其采用两个变压器耦合振荡器构成双模振荡器，每个变压器耦合振荡器中的升压变压器将第一MOS管的漏极电压摆幅进行倍增后再注入第二MOS管的栅极，从而在不增大振荡器的供电电压的情况下获得更大的栅极电压摆幅，提高双模振荡器的相位噪声性能。该多相位振荡器，由多个双模变压器耦合振荡器通过多相位耦合电路连接成莫比乌斯环，不仅可以产生多相位振荡信号，还可以提高整个振荡器的相位噪声性能。

摘要： The invention is related to an electrically tunable voltage-controlled oscillatory circuit, wherein the negative bias voltage (-Vcf') of a capacitance diode (5) needed for tuning the center frequency of the oscillatory circuit is generated on the basis of an electric oscillating signal (RFout) produced by the oscillatory circuit itself. Said oscillating signal is used for generating a negative voltage with a clamp/voltage multiplier type circuit (15) and it is adjusted to a desired value with an adjustment circuit (14), in which the values of the components (R2) can be permanently adjusted suitable in the tuning stage. Alternatively, the adjustment circuit (14) may include an active component (Q1) which can have an effect on the value of the negative bias voltage (-Vcf') during the use of the oscillatory circuit.

摘要： Voltage-controlled oscillator provided with a frequency-determining element and an oscillator loop having a phase-rotating network, in which the value of one or more elements depends on a control signal which is fed to a control input and with which the phase rotation and thereby the oscillator frequency can be changed. The oscillator is further provided with a phase control loop, at least comprising a phase-rotating network to the input of which the oscillator signal is fed, a phase detector to the two inputs of which the input signal and the output signal of said phase-rotating network are fed, and an amplifier which amplifies the output signal of the phase detector and feeds it to the control input of the phase-rotating network of the oscillator loop. The phase detector has an accurately known and temperature-independent input-output relation. The phase-rotating network of the phase control loop may be formed by the phase-rotating network of the oscillator loop (Fig. 2). Said oscillator loop may have at least two cascaded phase-rotating subnetworks, at least one of which has said phase control loop with phase detector and amplifier (Figs. 3, 4, 5).

摘要： A method for calibrating an oscillator in an electronic device and an electronic device configured for calibration are provided. Multiple signals are sent to the electronic device from another electronic device, such as from a host device. With knowledge of the time interval between the multiple signals, the electronic device may calibrate the oscillator in the electronic device. For example, the electronic device may be a USB-compliant electronic device. The USB-compliant electronic device may receive Start of Frame (SoF) signals from a host device, which in one USB implementation is received at 1 mSec intervals. The USB-compliant electronic device may count the output of the oscillator between receipt of different SoF signals in order to determine the frequency of the oscillator at different oscillator settings.

摘要： Embodiments of this application disclose a dual-mode oscillator and a multi-phase oscillator. In the dual-mode oscillator, switching between two operating modes is implemented by using a mode switching circuit, so that oscillation signals having two different bands can be obtained. Moreover, the dual-mode oscillator includes two transformer-coupled oscillators, and a step-up transformer in any transformer-coupled oscillator multiplies a drain voltage swing of a first MOS transistor and then injects a voltage signal to a gate of a second MOS transistor, so that a larger gate voltage swing is obtained without increasing a supply voltage of the oscillator, and phase noise performance of the dual-mode oscillator is improved. In the multi-phase oscillator, multiple dual-mode transformer-coupled oscillators are connected through multi-phase coupled circuits to form a Mobius loop, so that oscillation signals in multiple phases can be generated, and phase noise performance of the entire oscillator can be improved.
