The most common online technique for compensation of iR-drop is positive feedback [33-47]. The corresponding circuits depend on the concept of the potentiostat and are presented for the adder potentiostat (Fig. 2) and for the hybrid type (separate adder. Fig. 3). The simple idea behind is to add the potential drop Uq across Rq to the desired voltage so that they compensate each other. The current is measured by a current-to-voltage converter (CV in Figs. 2 and 3). The output of CV is...
