20120139764 | Continuous Time Sigma-Delta ADC with Embedded Low-Pass Filter - A filtering analog to digital converter (ADC) includes an integrator receiving at its input an analog input signal. A filtering capacitor at the input of the integrator filters out a large portion of out-of-band interferers in the analog input signal. The integrator produces an output that is quantized to produce a digital output. A feedback path between the quantizer output and the integrator input includes a digital to analog converter (DAC). | 06-07-2012 |
20140062740 | ANALOG TO DIGITAL CONVERTER WITH NOISE REDUCING FEEDBACK PATH - An analog to digital converter including a low pass filter element, a quantizer, and a digital to analog converter provide in a feedback path. The low pass filter element is configured to filter an analog input signal. The quantizer is configured to receive an analog output signal that is based on the filtered analog input signal and convert the analog output signal to a digital output signal. The digital to analog converter is configured to generate an analog feedback signal based on the digital output signal and selectively inject or absorb current associated with the feedback path to reduce noise associated with the digital to analog converter. The analog feedback signal is combined with the analog input signal at an input of the low pass filter element. | 03-06-2014 |

20110056398 | DIRECT IMPRINTING OF POROUS SUBSTRATES - Provided are methods of patterning porous materials on the micro- and nanometer scale using a direct imprinting technique. The present methods of direct imprinting of porous substrates (“DIPS”), can utilize reusable stamps that may be directly applied to an underlying porous material to selectively, mechanically deform and/or crush particular regions of the porous material, creating a desired structure. The process can be performed in a matter of seconds, at room temperature or higher temperatures, and eliminates the requirement for intermediate masking materials and etching chemistries. | 03-10-2011 |
20110059538 | DIFFRACTION GRATINGS COMPRISING POROUS MATERIALS AND DIFFRACTION-BASED SENSORS COMPRISING POROUS MATERIALS - Diffraction gratings comprising a substrate with protrusions extending therefrom. In one embodiment, the protrusions are made of a porous material, for example porous silicon with a porosity of greater than about 10%. The diffraction grating may also be constructed from multiple layers of porous material, for example porous silicon with a porosity of greater than about 10%, with protrusion of attached thereto. In some embodiments the protrusions may be made from photoresist or another polymeric material. The gratings are the basis for sensitive sensors. In some embodiments, the sensors are functionalized with selective binding species, to produce sensors that specifically bind to target molecules, for example chemical or biological species of interest. | 03-10-2011 |
