ABSTRACT:
Low jitter ring oscillators are disclosed. The oscillators obtain their low jitter through the use of gates (100) and interpolators (160) having time delays of superior stability. The stability is obtained with decoupling networks (140) and delay replica generators (222) that isolate power supply noise from critical circuit parameters.
