17 years agoI don't see anything but a first order Transfer Function, so what is the biquad for?
Moreover what is the input to the filter, the square pulses of the clock itself?? I can see one clock source, where is the other? I can only understand why the XOR is there, though it is not the best way for a phase comparator. Kaz
