AW: AW: VC Phaser using the LM13600

I don't think so. The group delay for both cases is exactly the
same. It's fairly constant for low freq, and then goes down for 
higher freq. The 180 degrees "phase difference" between the
two circuits is actually a signal inversion, *not* an additional
delay. (Always look at the delay, not the phase, in the first place.
Phase is quite ambiguous.)

Different implementations will differ because of different parasitics,
different nonlinearities etc.
