  • Patent number: 10749481
    Abstract: Aspects generally relate to reducing delay, or phase jitter, in high speed signals transmission. Variations in power supply to ground potential changes the amount of delay introduced by transmit circuitry into the signal being transmitted, resulting in jitter, or phase noise, in the transmitted signal. To reduce phase jitter, or phase noise, aspects disclosed include a variable impedance circuit coupled to the signal distribution network, the impedance level of the variable impedance circuit is adjusted in response to variation in the supply to ground potential, such that the delay introduced by the impedance compensates for changes in the delay due to variations in supply to ground potential, resulting in substantially constant delay.
