Fig. 5: MVM accuracy measurement results.

a 4-quadrant MVM results using the conventional four-phase reading scheme. b 4-quadrant MVM results using the single-phase reading scheme. c 2-quadrant MVM results (positive-only inputs) using the single-phase reading scheme. The black line in the plots is a y = x guide to the eye.
