The corresponding voltage Vt is compared with the "locked" signal, Vi, by the comparator. This returns a logic signal K to the SAR as follows: If Vt > Vi k=1; else k=0. If the voltage Vt generated by the DAC is bigger than Vi the test value is removed and a smaller value tried. Otherwise the test value is left and a another test value added.
