Latest Patents

One of his latest patents involves systems and methods for electronically scanned array antennas. This invention includes an array of antennas that features transmitter and receiver circuits. The transmitter comprises a digital-to-analog converter (DAC), splitter and filter circuits, mixer circuits, and antennas. The DAC circuit is responsible for converting a digital signal into an analog signal. The splitter and filter circuits then separate the frequencies of the analog signal into split signals. The mixer circuits multiply frequencies from the split signals by different frequencies of carrier signals to generate modulated signals, which are converted by the antennas into radio frequency (RF) signals. The receiver includes antennas, mixer circuits, a summing circuit, and an analog-to-digital converter (ADC). The antennas in the receiver capture RF signals, converting them into electrical signals. The mixer circuits multiply frequencies from these electrical signals with different frequencies of carrier signals. The outputs from the mixer circuits are summed by the summing circuit to create a summed signal that is converted to digital by the ADC. Another notable patent is an analog-to-digital converter or digital-to-analog converter data path with deterministic latency. This circuit system includes an analog-to-digital converter circuit, a digital-to-analog converter circuit coupled to the analog-to-digital converter circuit, and a variable latency circuit that generates a deterministic latency in an output signal based on a measured latency of the data path.
