Title: self-bias PLL vs ICO PLL Post by newic on Mar 21st, 2012, 8:14pm self biased PLL is widely used but the jitter performance is not that good if compare to ICO type PLL (better PSRR). Is it true and why?

Title: Re: self-bias PLL vs ICO PLL Post by raja.cedt on Mar 22nd, 2012, 1:17am what do you mean by ICO? is it current controlled oscillator. If so you are wrong because self bias pll is based on CCO (may be some people cal this is regulator based vco). Thanks, Raj.

Title: Re: self-bias PLL vs ICO PLL Post by newic on Mar 29th, 2012, 6:58pm yes, comparing to CCO type, which is regulator based VCO. what are the pros & cons on this regulator based VCO?
