    摘要： A differential oscillator includes a differential circuit and a transformer-coupled band-pass filter (BPF) coupled between first and second output nodes. The BPF includes a coupling device coupled between the output nodes and a transformer including first and second windings in a metal layer of an IC. The first winding includes first and second conductive structures coupled to the first output node and a voltage node, respectively, and a third conductive structure including first and second extending portions connected to the first and second conductive structures, respectively. The second winding includes a fourth conductive structure including a third extending portion coupled to the voltage node and a fourth extending portion coupled to the second output node. The third extending portion is between the second conductive structure and the first extending portion, and the fourth extending portion is between the first conductive structure and the second extending portion.

    摘要： A magnetoresistive effect oscillator executes a first step of applying a current, which has a first current density larger than a critical current density JO for oscillation, to a magnetoresistive effect element for a time TP, and then executes a second step of applying a current, which has a second current density JS smaller than the first current density and not smaller than the critical current density JO for oscillation, to the magnetoresistive effect element. The following formulae (1), (2) and (3), or the following formulae (1) and (4) are satisfied on an assumption that an average value of the first current density during the time TP in the first step is JP, a critical current density for magnetization reversal of the magnetoresistive effect element is JR, and a magnetization reversal time of the magnetoresistive effect element is TR: 0.1 × T R  ( J R - J O ) J p - J S

    摘要： Systems and methods for biasing frequency oscillators to minimize phase noise are disclosed. The system may comprise a tank circuit having an inductor, at least a first coupling capacitor and a second coupling capacitor. The system may further comprise a varactor circuit electrically connected to the first coupling capacitor and the second coupling capacitor. The system may further comprise at least one first metal oxide semiconductor (MOS) device electrically connected in shunt with the tank circuit and a bias voltage. The at least one first MOS device may be electrically connected to a first gate bias voltage configured to bias the at least one first MOS device such that a first gate-to-source voltage of the at least one first MOS device remains below the first threshold voltage.

    摘要： A transformer is described. The transformer includes a primary coil and a first secondary coil. A first coupling occurs between the first secondary coil and the primary coil. The transformer also includes a second secondary coil. A second coupling occurs between the second secondary coil and the primary coil. The first secondary coil is separated from the second secondary coil to prevent coupling between the first secondary coil and the second secondary coil. A first width of the first secondary coil is configured independently of a second width of the second secondary coil.
