Sa zicem ca ajungem la 3v tensiune pe acumulator , ar trebui ca mosfetul sa fie complet deschis la tensiunea asta, gasim un asa mosfet? de asemenea operationalul ar trebui sa fie capabil sa dea 3v la iesire deci un op amp cu iesire rail to rail.

Schema de la inceputul paginii satisface exact criteriile astea, cu tipurile indicate de AO si MOS.
