摘要： The present application relates to a differential oscillator circuit. The differential oscillator circuit comprises a pair of transistors with control terminals biased by a common biasing voltage. The differential oscillator circuit further comprises a transformer having a primary coil coupled between first current terminals of the transistors and a secondary coil coupled in a closed series circuit with two varactors, which are arranged for being tuned by a first common tuning voltage. The differential oscillator circuit further comprises a series circuit comprising two further varactors coupled in series to second current terminals of the transistors. The two further varactors are arranged for being tuned by a second common tuning voltage.

摘要： The present invention provides a voltage waveform shaping oscillator, including a signal source and a coupling transformer. An output end of the signal source is connected to an input end of the coupling transformer, and an input end of the signal source is connected to an output end of the coupling transformer. The signal source is configured to: receive, by using the input end of the signal source, a quasi-square wave signal output by the output end of the coupling transformer, generate an original signal based on the quasi-square wave signal, and send the original signal to the input end of the coupling transformer by using the output end of the signal source, where the original signal is an oscillating signal, and the output end of the signal source is an output end of the oscillator and is configured to output the original signal. The coupling transformer is configured to: receive the original signal by using the input end of the coupling transformer, perform filtering processing on the original signal to obtain the quasi-square wave signal, and send the quasi-square wave signal to the input end of the signal source by using the output end of the coupling transformer. The voltage waveform shaping oscillator is configured to reduce phase noise of an oscillator.

摘要： Certain aspects of the disclosure are directed to electrostatic discharge protection of an integrated circuit clock. According to a specific example, circuitry includes a direct-current power supply, a voltage-controlled oscillation (VCO) circuit, an electrostatic protection circuit, and a voltage regulator. The VCO circuit has an oscillation frequency and includes an amplification circuit and capacitance circuitry. The electrostatic protection circuit is arranged to connect power to the VCO circuit while reducing variation in the oscillation frequency of the VCO circuit resulting from electrostatic energy. The voltage regulator is connected between the direct-current power supply and a power supply connection at which the direct-current power is connected to the VCO, and is configured to mitigate an imbalance of electric charges from adversely altering a tuning capacitance of the VCO established by the capacitance circuitry.

摘要： Provided herein are apparatus and methods for using tuning information to adaptively and dynamically modify the parameters of an RF signal chain. The tuning information from an oscillator core, having multiple oscillators, adaptively tunes parameters of system components within a signal chain. In this way the system components are tuned to operate within a band tailored to the signal and to the oscillator core. In addition, RF impedances can be matched and power added efficiency can be enhanced in an area efficient monolithic integrated circuit.

摘要： Le dispositif d'oscillateur local comporte un module oscillateur (OSC) possédant un premier élément inductif (L) et un élément capacitif (C) montés en parallèle, et un diviseur de fréquence (fDiv) couplé au module oscillateur (OSC) pour délivrer un signal d'oscillateur local (LO, LO1-LO4). Le dispositif d'oscillateur local (DIS) comporte un autotransformateur (TR) comprenant le premier élément inductif (L) et deux deuxièmes éléments inductifs (L1, L2) respectivement couplés aux bornes (La, Lb) du premier élément inductif (L) et à deux bornes de sortie de l'autotransformateur (OUT1, OUT2), lesdites bornes de sortie (OUT1, OUT2) étant par ailleurs couplées à des bornes d'entrée (IN1, IN2) du diviseur de fréquence (fDiv).
