Abstract: In at least some embodiments, a system comprises a frequency generator configured to generate a second clock signal having a second frequency using a first clock signal having a first frequency. The second frequency is offset from the first frequency and each of a plurality of harmonic frequencies of the second frequency is offset from a harmonic frequency of the first frequency. The system also includes a power converter configured to produce a power signal that at least partially corresponds to the second frequency. The system further comprises an analog-to-digital converter (ADC) configured to sample and convert analog voltages at the first frequency. The ADC is powered by the power signal.

Abstract: In an integrated circuit (IC), a semiconductor substrate has a first side and an opposite second side. The second side has a trench. Circuitry is on the first side. An inductive structure is within the trench. The inductive structure is connected to the circuitry through vias in the semiconductor substrate. The semiconductor substrate is mounted on a package substrate. At least a portion of the inductive structure contacts the package substrate. The circuitry is coupled to the inductive structure through wires to the package substrate.

Abstract: A transducer has an input and produces a mechanical output, wherein the magnitude of the mechanical output of the transducer is dependent on the frequency and magnitude of current at the input. A driver for the transducer includes a device having a transfer function associated with the device, the device having a device input and a device output, the device output being connectable to the input of the transducer and the device input being connectable to a power source. The device attenuates the current output at a frequency that causes a peak in the magnitude of the mechanical output of the transducer.
