the reference in that case is a CAPACITOR

it measures the frequency shift, not the absolute frequency

Thus it is able to self-calibrate and auto-zero

To see what this circuit would do in real, you must go down in simspeed. Now its in subsampling at 1s/s and generates just chaotic nonsense. Go down to 30us/s and restart simulation. This is one of the most importante things to understand, take your time in simulation and never do subsampling! I know how difficult it is to be patitent, but its a must to be and to understand!
