Narrative:

We departed runway 18C shortly after an A320. Immediately after rotation we ran into wake turbulence. The stick shaker activated for a second or two and then cleared. I was in the process of raising the landing gear and selecting speed mode on the fcp and was aware of the stick shaker motor sound. I asked the first officer about it later and he said that the stick shaker had activated but the speed was nowhere near the barber pole and the plane had not exhibited any dangerous flying characteristics. By the time I got a look at the airspeed...when confirming 'climb' on the pfd it was about half was between V2 and vt (about 170 KIAS). We climbed out uneventfully. It was a warm evening with calm winds...just the sort of conditions to keep the wake vortices over the runway where we ran into them. The stick shaker activates based on angle of attack and change in angle of attack. The way the vortex hit the aircraft must have activated the logic to give a brief stick shaker.
