He has made significant contributions to the field of technology, particularly in the area of timing and clock generation circuits. With a total of two patents to his name, Johnson's work showcases his expertise and innovative spirit.
Latest Patents
Johnson's latest patents include a Timing Generator and a Clock Holdover Circuit. The Timing Generator patent describes a circuitry that taps a DS0 data stream to output a timing signal for terminal multiplexers. This invention ensures that even if the data bit stream is lost, proper clocking signals continue to be provided. The composite clock features a bit clock at 64 KHz and a byte clock at 8 KHz. To address phase shift issues over long distances, the invention incorporates a phase adjustment mechanism that gives the appearance of advancing the signal in phase.
The Clock Holdover Circuit patent presents a solution for providing a replacement clock signal that remains stable despite variations in time and temperature. This circuit utilizes a single component that is time and temperature dependent, ensuring accuracy by selecting parameters within desired tolerances. The combination of digital circuitry and a local crystal frequency source allows for phase consistency upon the loss and return of a reference clock signal. The stored offset frequency is used to drive a frequency synthesizer, ensuring an acceptable replacement clock signal is maintained indefinitely.
