H. Mohammed Shuaeb Fazeel 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).

  • DC Offset Correction with Low Frequency Signal Support Circuits and Methods
    Publication number: 20150054560
    Abstract: DC offset correction is provided with low frequency support. A first input terminal for receiving an input signal is selectively coupled to a resistance and a capacitor that are series coupled between the first input terminal and a corresponding output terminal. In a calibration phase, the series resistance is coupled between the input terminal and the capacitor and an average voltage level of the input is stored on capacitor. In a signal processing phase, the charged capacitor is coupled in series between the input terminal and the output terminal while the resistance is bypassed. The output signal obtained contains the high and low frequency components of the input signal, while the DC offset in the input signal is removed from the output signal. A differential circuit and methods are disclosed. Additional embodiments are disclosed.
