Abstract
A method for cancelling load regulation, based on level shifting the reference, is proposed. In this architecture, the load current is monitored, sensed, and used to dynamically adapt the effective value of the reference voltage. The proposed architecture reduced a 2.5% load regulation droop to a mere 0.2%, without compromising system stability.
