    Abstract: An electronic system comprises a first and a second oscillator that are mutually cross-coupled and have one and the same resonant frequency, each oscillator comprising an electrical resonator, an active cell having a negative small-signal resistance linked to the electrical resonator, an electric power supply terminal of the active cell, an output for an oscillation signal and a terminal for connection to a ground point, wherein: the electric power supply terminal of the second oscillator and the terminal for connection to a ground point of the first oscillator are linked to one and the same point, termed dynamic ground; and the system also comprises a differential amplifier forming, with the active cell of one of the oscillators, a feedback loop designed to keep the potential of the dynamic ground point at a constant level, dependent on the reference voltage.

    Abstract: An apparatus includes a spin torque oscillator, a sensor, and a processing unit. The spin torque oscillator is configured to receive a current and to generate a microwave output signal. The sensor is configured to detect the microwave output signal and to detect changes to frequency of the detected microwave output signal responsive to changes in an external magnetic field. The processing unit is configured to receive a sensed signal from the sensor. The processing unit is further configured to process the sensed signal and the changes to the frequency to determine magnitude and direction associated with the external magnetic field.

    Abstract: An oscillator circuit includes first and second oscillators arranged in a series configuration between a supply voltage node and a reference voltage node. The first and second oscillators are configured to receive a synchronizing signal for controlling synchronization in frequency and phase. An electromagnetic network provided to couple the first and the second oscillators includes a transformer with a primary circuit and a secondary circuit. The primary circuit includes a first portion coupled to the first oscillator and second portion coupled to the second oscillator. The first and second portions are connected by a circuit element for reuse of current between the first and second oscillators. The oscillator circuit is fabricated as an integrated circuit device wherein the electromagnetic network is formed in metallization layers of the device. The secondary circuit generates an output power combining power provided from the first and second portions of the primary circuit.

    Abstract: Methods and systems are provided for adaptively configuring voltage-controlled oscillator (VCO) arrays, such as to reduce mismatches among the VCOs. A plurality of voltage-controlled oscillators (VCOs), connected in parallel to a common control input, and with each VCO outputting an oscillating signal based on the common control input and an adjustment input, may be configured to reduce mismatches among the VCOs. The plurality of VCO may be configured by adjusting at least one operational parameter applicable to interconnection paths connecting outputs of the plurality of VCOs; measuring a mismatch between signals at the outputs of the plurality of VCOs with respect to a first signal parameter; and adjusting a first operational parameter applicable to one or more of the plurality of VCOs to reduce mismatch between signals at the outputs of the plurality of VCOs with respect to a first signal parameter.

    Abstract: Apparatus and methods for switch-coupled oscillators are disclosed. In certain implementations, an oscillator system includes a primary oscillator, one or more auxiliary oscillators, one or more switching circuits, and an oscillator control circuit. The oscillator control circuit can be used to control the one or more switching circuits to selectively couple the primary oscillator to all or a portion of the one or more auxiliary oscillators. The oscillator control circuit can also disable any auxiliary oscillators that are decoupled from the primary oscillator to reduce power consumption. By selecting a number of auxiliary oscillators to couple to the primary oscillator, the oscillator system can have a configurable phase noise versus power consumption profile.
