Rav Aha Bar Rav was a talmid-haver of Ravina (6th generation of amoraïm), and also a contenporary of Ravina II (7th) (source).
So it's seems that Rav Aha is not the son of Rav (ie Rabbi Abba bar Aybo, who was in 1st).
So, who is this "Rav" ?

In it's "לחקר שמות וכינויים בתלמוד", page 63, Rav Margolies explain that "Rav" was the name of his father, as there was other with this name, as "Rav Bar Sheva".
