Azita Emami-Neyestanak has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9215114
    Abstract: A receiver architecture is disclosed which employs an RC double-sampling front-end and dynamic offset modulation technique. A low-voltage double-sampling technique provides high power efficiency by avoiding linear high-gain elements conventionally employed in typical transimpedance-amplifier (TIA) receivers. In addition, a demultiplexed output of the receiver helps save power in the subsequent digital blocks. Various applications are described including optical receivers, electrical on-chip interconnects, as well as pulse amplitude modulation. The receiver can be implemented in CMOS and is scalable and portable to other technologies.

  • Publication number: 20140308208
    Abstract: Methods are described and related devices, compositions, and systems, in which a caged compound is administered to a biological environment, the caged compound being caged with a long wavelength absorber, the long wavelength being a wavelength greater than or equal to 750 nm; and irradiating the biological environment to excite the long wavelength absorber with light at a wavelength in a range from 900-1100 nm, thus decaging the compound.

  • Patent number: 7602869
    Abstract: Clock synchronization and data recovery techniques are disclosed. For example, a technique for synchronizing a clock for use in recovering received data comprises the following steps/operations. A first clock (e.g., a data clock) is set for a first sampling cycle to a first phase position within a given unit interval in the received data. A second clock (e.g., a sweep clock) is swept through other phase positions with respect to the first phase position such that a transition from the given unit interval to another unit interval in the received data is determined. A sampling point is determined based on measurements at the phase positions associated with the second clock. The second clock is set to the phase position corresponding to the sampling point such that data may be recovered at that sampling point.
