Latest Patents

One of his latest patents is the Channelized Analog-to-Digital Converter. This invention is a waveform acquisition system that captures and digitizes a wideband electrical signal through a bank of front-end filters, frequency down converters, and conventional digitizers (A/D converters). A software algorithm reconstructs the composite input signal and applies the necessary corrections to remove the effects of hardware impairments. This approach is possible because it uses a class of filters that exhibit the quality of perfect waveform reconstruction, allowing signals whose spectral components overlap multiple filter bands to be faithfully reconstructed. A calibration generator switched into the input port serves as a reference for quantifying and removing hardware errors. The channelized analog-to-digital converter (ADC) effectively multiplies the bandwidth and sampling rate of the conventional digitizer performance in a single channel by the number of channels in the system.

Another significant patent is the High-Speed Signal Processor. Similar to his previous invention, this system captures and digitizes a wideband electrical signal through a bank of front-end filters, frequency down converters, and conventional digitizers (A/D converters). The software algorithm reconstructs the composite input signal and applies necessary corrections to mitigate hardware impairments. The use of digital local oscillators enables a compact, low-power, monolithic architecture, enhancing the overall performance of the system.
