Abstract :
A comparison is made of the effects of random parameter variations on the periodic mismatches in three different high-speed ring oscillators generating multi-phase clock signals. These variations in the phase-to-phase periods manifest themselves in the form of jitter which is deterministic in nature. Simulations have also been carried out to demonstrate the improvement in the jitter performance of these oscillators with device scaling
