  • Patent number: 11393520
    Abstract: The embodiments described herein provide for methods and systems for removing power supply induced jitter from a Phase Lock Loop to provide a Power Supply Induced jitter-free clock signal to a system-on-a-chip and GDDR6 DRAM interface. In operation, a circuit reduces a DC offset between a reference voltage and a voltage regulator output to identify low frequency noise on the voltage regulator output to apply as negative feedback to reduce the low frequency noise on the voltage regulator output. The bandwidth of the circuit is increased to detect high frequency noise, which is applied as negative feedback on the voltage regulator output. Very high frequency noise is then detected and applied as negative feedback to the voltage regulator output. The circuit outputs a regulated output equal to the reference voltage and immune to the low, high, and very high frequency noise of power delivery network supply to the regulator.
