Abstract
A digital active diode circuit for letting current pass in one direction and substantially blocking current in the opposite direction is presented. The circuit contains switching means comprising an array of switches, a first comparison unit coupled to the digital active diode circuit input and output. The first comparison unit updates its output if the difference between their inputs is higher than a first threshold voltage, and a second comparison unit being coupled to the digital active diode circuit output and input. The second comparison unit updates its output if the difference between its inputs is lower than a second threshold voltage. The switching means switches on or off at least one switch based on the comparisons performed by the first comparison unit and the second comparison unit and wherein the first threshold voltage is different from the second threshold voltage.
