Abstract
A device and method for sensing an inductor current in an inductor is provided that generates a voltage signal proportionate to the inductor current if the inductor is connected to a positive supply and simulates the inductor current if the inductor is not connected to the positive supply. The voltage signal may be generated by sampling an input voltage from the inductor onto a capacitor if the inductor is connected to the positive supply. The inductor current may be simulated by generating a simulation current and pushing the simulation current onto the capacitor.
