    摘要: A continuous wave (CW) integrator is employed within a compressive receiver to improve the sensitivity of the compressive receiver to CW signals. The CW integrator circuit partitions the bandwidth of the compressive receiver into a series of contiguous bins and integrates any signals residing within these bins over many sweeps of the compressive receiver bandwidth. By sampling and integrating CW signals present in the compressive receiver bandwidth, the CW integrator circuit improves the sensitivity of the compressive receiver by a factor approximately equal to 10 log .sqroot.N, where N is the number of integrations performed.

    摘要: Systems and methods are provided for the manipulation of a polarizable object with a pair of elongated nanoelectrodes using dielectrophoresis. The nanoelectrodes can be carbon nanotubes and are coupled with one or more time-varying voltage sources to create an electric field gradient in a gap between the nanotubes. The gradient induces the movement of a polarizable object in proximity with the field. The nanotube pair can be used to trap a single polarizable object in the gap. A method of fabricating a nanoelectrode dielectrophoretic system is also provided. Applications extend to self-fabricating nanoelectronics, nanomachines, nanochemistry and nanobiochemistry. A nanoelectrode dielectrophoretic system having an extended nanoelectrode for use in applications including the self-fabrication of a nanowire, as well as methods for fabricating the same, are also provided.

    摘要: A multifinger carbon nanotube field-effect transistor (CNT FET) is provided in which a plurality of nanotube top gated FETs are combined in a finger geometry along the length of a single carbon nanotube, an aligned array of nanotubes, or a random array of nanotubes. Each of the individual FETs are arranged such that there is no geometrical overlap between the gate and drain finger electrodes over the single carbon nanotube so as to minimize the Miller capacitance (Cgd) between the gate and drain finger electrodes. A low-K dielectric may be used to separate the source and gate electrodes in the multifinger CNT FET so as to further minimize the Miller capacitance between the source and gate electrodes.

    摘要: An ultra-linear chirp generator includes a voltage controlled oscillator (VCO) having a tuning characteristic which is naturally nonlinear, a linear ramp generator which generates a linearly ramping output signal having a linear slope characteristic with respect to time, a polynomial correction waveform generator which generates a polynomial correction signal, and a summer which is responsive to and sums the linearly ramping output signal and the polynomial correction signal. The summer generates a VCO tuning signal for tuning the VCO. The tuning signal corresponds to the linearly ramping output signal predistorted with a nonlinearity opposite to the natural nonlinearity of the VCO tuning characteristic. The linear chirp generator also includes a phase locked loop which is responsive to the output signal of the VCO and which has a reference frequency which is related to the repetition rate of the output signal of the VCO.
