Abstract
A circuit has an operational voltage supply node that carries an operational voltage having an operational voltage value, a reference voltage supply node that carries a reference voltage having a reference voltage value, and a sub-circuit and switching circuit between the operational voltage supply node and the reference voltage supply node. The switching circuit is in series with the sub-circuit and controls a current through the sub-circuit based on a difference between the operational voltage value and a nominal operational voltage value.
