IMHO, it's easier to put this into some Amplifier in feedback loop.
As it's already been pointed out, there're 2 TL loops 1) M9,10,4,2 2) M7,8,3,1
M6 is the bias current source and Vin will be adjusted by the feedback loop such that current through M1 and M2 will be equal so that Vout stays around mid-rail. When that happens, current through M3,4 will be roughly equal as well, i.e., both equal to Ib roughly.
