发明名称 Leakage-current compensation for a voltage regulator
摘要 In one embodiment, a method includes generating a drive current. Generation of the drive current results in a first leakage current, and the drive current and first leakage current each flow into a first node. The method also includes generating a second leakage current and amplifying the second leakage current to generate a leakage-compensation current. The leakage-compensation current flows away from the first node.
