20090267699TIMING OSCILLATORS AND RELATED METHODS - Timing oscillators as well as related methods and devices are described. A timing oscillator may include a mechanical resonating structure with major elements and minor elements coupled to the major element. The timing oscillator can generate stable signals with low phase noise at very high frequencies which allows a timing oscillator to be used effectively in a number of devices including computers and mobile phones for time and data synchronization purposes. The signal generated by the timing oscillator can be tuned using a driver circuit and a compensation circuit.10-29-2009

20100039126NANOCHANNEL-BASED SENSOR SYSTEM FOR USE IN DETECTING CHEMICAL OR BIOLOGICAL SPECIES - A sensor system for detecting a chemical or biological species includes a sensing element and a bias and measurement circuit. The sensing element includes nanochannels, each having an outer surface functionalized to chemically interact with the species to create a corresponding surface potential, and each having a sufficiently small cross section to exhibit a shift of a differential conductance characteristic into a negative bias operating region by a shift amount dependent on the surface potential. The bias and measurement circuit applies a bias voltage across two ends of the nanochannels sufficiently negative to achieve a desired dependence of the differential conductance on the surface potential, wherein the dependence has a steeply sloped region of high amplification substantially greater than a reference amplification at a zero-bias condition, thus achieving relatively high signal-to-noise ratio. The bias and measurement circuit converts the measured differential conductance into a signal indicative of presence or activity of the species of interest.02-18-2010
