Abstract
The leakage current correction circuit uses a dummy device Mleak to detect leakage current. The dummy device is a scaled down version of the pass element Mpass. A current router is used to either gain up the dummy leakage current and apply it to the output Vout or simply dump the small un-gained current to ground GND.
