摘要： Briefly, in accordance with one embodiment of the invention, a resonator such as an electromechanical resonator may be coupled with a cancellation network to reduce and/or cancel an anti-resonance effect in the resonator, which may be due to, for example, a static capacitance inherent in the resonator. Cancellation of an anti resonance effect from the resonator response may allow a resonance effect of the resonator to be a predominant effect to allow the resonator to be utilized as a bandpass filter having a relatively higher Q, for example in a bandpass sigma-delta modulator that may be utilized in a digital RF receiver.

摘要： Described herein is a method for obtaining a three-dimensional nanostructure array on an aluminum substrate. The method includes anodizing the aluminum substrate; forming an oxide layer on the aluminum substrate; texturizing the aluminum substrate; etching the oxide layer from the aluminum substrate to expose the texturized aluminum substrate; and forming a three-dimensional aluminum nanostructure array on the aluminum substrate. The three-dimensional nanostructure array, coated with a light absorber, is utilized in a thin film solar cell or photovoltaic cell.
