Abstract :
This paper deals with the inductor-current monitoring for switching regulators. Conventional current sensors based on the mirroring principle are first considerated. Then, a new circuit that reaches improved performance respect to the existing current-sensing schemes is proposed. The operation of the above mentioned current sensors are discussed and evaluated by means of time-domain computer simulations.
