    摘要: A parametric feedback oscillator includes a resonator which has at least one transduction element and at least one electromechanical resonating element. The resonator is configured to accept as input a parametric excitation signal at a frequency 2ω0 and to provide a resonating output signal at a frequency ω0. A cascaded feedback path in any electrically coupled cascade order includes at least one non-linear element, at least one phase shifter electrically, and at least one amplifier. The cascade feedback path is configured to receive as input the resonating output signal at a frequency ω0 and configured to provide as output a feedback path signal as the parametric excitation signal at a frequency 2ω0 to the resonator. A parametric feedback oscillator output terminal is configured to provide the resonating output signal at the frequency ω0 as an output signal. A method of causing a parametric feedback oscillation is also described.

    摘要: A displacement transducer in which relative displacement between a magnet and a Hall junction is sensed. Magnetic flux from the magnet is linked to the Hall junction in a direction perpendicular to the flow of current through the Hall junction. Relative displacement between the magnet and the Hall junction causes a change in the magnetic flux linked to the Hall junction which in turn causes a change in transverse voltage across the Hall junction. A signal representative of this voltage change is output from the transducer. The transducer may be part of a NEMS or MEMS.
