Latest Patents

Mandell J Mangahas holds a patent for a system titled "Baseband digital offset correction." This signal processing system includes a main digital-to-analog converter (DAC) that receives a digital baseband signal and converts it into an analog signal. The system features a connection circuit for receiving the analog signal and an output terminal. An analog filter is coupled between the connection circuit and the output terminal to filter the analog signal. Additionally, a calibration circuit is included to set an offset voltage level. This calibration circuit comprises an approximation circuit that operates during a calibration mode to determine and store the offset voltage level as a digital offset signal. An offset DAC is also part of the system, converting the digital offset signal into the offset voltage level. The connection circuit subtracts the offset voltage level from the analog signal, enhancing the accuracy of the output.
