Abstract
A control circuit for substrate potential regulation for an integrated circuit device. The control circuit includes a current source configured to generate a reference current. A variable resistor is coupled to the current source. The variable resistor is configured to receive the reference current and generate a reference voltage at a node between the current source and the variable resistor. The reference voltage controls the operation of a substrate potential regulation circuit coupled to the node.
