Abstract :
In this paper, we demonstrate that it is possible to design circuits insensitive to power supply noise at frequencies in the range of 200 MHz to 500 MHz. We show that by using proper filter design at the beginning of the clock distribution network we increase the clock to data tracking and mitigate the impact of power supply noise on maximum operating frequency. We prove the theory with measurements using a 130 nm processor as an experimental validation vehicle.
