The simulation indicates that the TAC capacitor charging current is far from constant whilst charging. This is due to the use of saturated switches rather than current steering switches. The capacitor charging current is poorly controlled. So in this respect your circuit fails miserably.
So if I'm understanding correctly, the non linearity is due to the uncontrolled current flowing from the collectors to the bases of saturated transistors, that changes the magnitude of charging current in uncontrolled way. I was trying to use a sungle supply, but now I'm starting to see the limits of my implementations.
