When the phase modulates, IMD occurs. The spectrum of phase IMD contains the same frequency components as amplitude IMD, but their phases differ by pi/2. AIMD is usually associated with signal-induced gain variations (e.g., transistor beta nonlinearity); PIMD is usually associated with signal-induced variations in shunt C (e.g., Cc-b). If you want to crunch the numbers see Cherry, "Amplitude and Phase of Intermodulation Distortion," JAES, May 1983.For an interesting discussion of cathode followers vs anode followers driving capacitive loads at high f's, see Keen, "Anode-Follower Derivatives," Wireless Eng, Jan 1953. Hint: one does better on negative cycles, the other on positive cycles.
For cathode followers driving C with large signals see Cocking, "Cathode-Follower Dangers," Wireless World, Mar 1946.
