Original Abstract Submitted

embodiments herein relate to a circuit for evaluating the ground voltage of each circuit partition of a number of circuit partitions, one partition at a time. once the ground voltage is determined, a corresponding code is stored to control a leakage circuit coupled to the ground node. the leakage circuit provides a leakage current based on the code to offset the ground voltage to a target voltage, which may be common for each of the partitions. the circuit can include a voltage source which supplies a stair step increasing voltage to a comparator. the comparator compares the voltage of the voltage source to the ground node voltage and provides an output which changes when the two input voltages are approximately equal, within a tolerance. the circuit may include a finite state machine for managing the process.
