Latest Patents

One of her latest patents is titled "Fully integrated offset compensation feedback circuit." This invention describes an offset correction analog circuit capable of compensating for the offset of a digital baseband. The circuit utilizes analog means to receive an output differential signal from a differential signal path, which may include a baseband filter used in digital communication systems. The output differential signal is processed through an analog integrator to generate a pulsed signal based on the polarity of the output differential signal. This pulsed signal is then integrated into a switched capacitor, resulting in a differential compensation offset signal that can be summed with the input differential signal.

Another significant patent is "Multiple repair size redundancy." This invention involves a Random Access Memory that incorporates a redundancy scheme. In this scheme, redundant memory elements are organized into various sizes of redundancy patches. The number of lines in each patch is selected based on the size of the defect detected during programming, allowing for efficient memory repair.
