Hello,
How can I model the second order sigma delta for the fractional pll.
How I can I show the bit sequence which is fed to the divider has LSB's changing from 1 to 0 which provides the average value of the division factor required.And how to print the average value.
Is there any specific equation set for this.
Can you give the source where I can get a matchcad model for this purpose.I have a model of sigma delta converter which plots the quantization noise plot with respect to frequency.How is this applicable to fractional pll

regards
dhiraj
