Latest Patents

One of Ryan's latest patents is a "Pulse output direct digital synthesis circuit." This invention involves a clock signal generator that responds to a frequency control word and a reference clock signal. The generator produces an output clock signal with a frequency that is less than the reference clock frequency. The design includes a modulo-N counter that generates a phase-indication signal, which is crucial for the operation of the clock edge selector. This selector determines the appropriate edge of the reference clock signal to toggle the output clock signal.

Another significant patent is focused on "Systems and methods for the reduction of peak to average signal levels of multi-bearer single-carrier and multi-carrier waveforms." This invention addresses the challenge of reducing peak to average signal levels in communication systems. It offers methods that can manipulate waveform statistics without expanding the spectral bandwidth of allocated channels. The techniques are applicable to both single and multi-carrier systems, enhancing the efficiency of existing RF transmitters.
