Abstract: System and method for increasing the frequency tuning range of a RF/microwave LC oscillator. An electronic communications device includes a controller to regulate the operation of the electronic communications device, a modem coupled to the controller, a radio frequency unit coupled to the controller and to the modem, an oscillator coupled to the controller and to the radio frequency unit, and an amplifier coupled to the radio frequency unit. The oscillator produces a timing and reference signal for the radio frequency unit based on control information from the controller. The oscillator includes a multi-tap inductor that may controllably alter its effective inductance to change the timing and reference signal provided to the radio frequency unit.

Abstract: System and method for increasing the frequency tuning range of a RF/microwave LC oscillator. A preferred embodiment comprises a voltage controlled oscillator (VCO) configured to generate an output signal at a frequency that is dependent upon a magnitude of an input voltage level and an effective inductance of an inductive load and a variable inductor coupled to the VCO. The variable inductor comprises a primary inductor coupled to the VCO to produce a magnetic field based upon a current flowing through the primary inductor and a secondary inductor magnetically coupled to the primary inductor, the secondary inductor to affect the magnitude of the effective inductance of the primary inductor.

Abstract: Systems are provided for producing a low frequency filter pole. A first bond pad is coupled to a power source. A second bond pad is inductively connected to the first bond pad by a first bond wire. A capacitor is connected to the second bond pad. A third bond pad is inductively connected to the second bond pad by a second bond wire. The second bond wire, in conjunction with the capacitor, forms a low frequency filter pole to mitigate noise in a regulated signal provided at the third bond pad.

Abstract: An apparatus for characterizing impedance presented to a write driver device in a write head assembly for use with an electromagnetic storage product includes: (a) a test impedance unit coupled with the write driver device; and (b) a measuring unit coupled with the test impedance unit. The measuring unit receives a measured parameter associated with the test impedance unit and compares the measured parameter with a reference parameter. The measuring unit indicates a result of the comparing.
