Title: Psudo differential ring oscillator - bias voltage equation Post by cmospll on May 25th, 2015, 10:26am Hi, I am new to PLL design. I am trying to understand the exact relationship between the bias voltage, bias current of a current starved psudo-differential ring oscillator. Attaching a screenshot for clarity. Guidance/Help is highly appreciable. - cmospll |
Title: Re: Psudo differential ring oscillator - bias voltage equation Post by loose-electron on May 27th, 2015, 8:19am such methods work on paper but tend to be a noise and jitter problem in silicon. if this is going to be a real piece of silicon I suggest you research other design alternatives google: Maneatis ring oscillator that will get you started |
