Latest Patents
Johnson holds a patent for an "Apparatus and methods for digital-to-analog conversion." This innovative apparatus is designed to convert a digital input signal into an analog signal for transmission. The input signal can include multiple carrier signals, and it employs a series of delta-sigma modulation loop circuits arranged in increasing order of operating frequency. This design effectively reduces the word length of the input signal. Additionally, a tuning circuit adjusts the signal frequency to a transmitting frequency, facilitating conversion to analog by a digital-to-analog converter. The first loop circuit utilizes CMOS gates, while the second loop circuit and the tuning circuit are implemented using indium phosphide gates. This apparatus allows for high-resolution, wide-band RF multiple-carrier signals to be re-quantized to lower-resolution signals while maintaining an acceptable signal-to-noise ratio. Johnson's patent represents a significant advancement in the field of signal processing.
