Title: David Coyne: Innovator in Signal Modulation and Logic System Security
Introduction
David Coyne is a notable inventor based in Glenrothes, GB. He holds a total of 8 patents that showcase his contributions to the fields of signal modulation and logic system security. His innovative work has made significant strides in enhancing technology and security measures.
Latest Patents
One of David's latest patents is a signal modulator designed for modulating at least one input signal. This modulator features an adaptive ramp generator that receives a clock signal, providing a ramp signal with a profile that adjusts in each clock cycle. The modulator can accept multiple input signals, including a first and second signal derived from a single source, with the second signal being a 180-degree phase shift of the first. Additionally, the modulator identifies the input signal with the highest amplitude and adjusts the ramp signal accordingly.
Another significant patent is a logic system that exhibits resistance to side-channel attacks by maintaining a closed clock-data eye diagram. This invention improves the security of logic systems by minimizing observable features that could be exploited by intruders. The technique involves using a randomized clock to ensure that the clock eye diagram remains closed, thereby enhancing security without significantly reducing the system's maximum operating speed.
