Abstract

A first active element has its first terminal coupled to a first power-supply terminal, its second terminal coupled through a resistor to a second power-supply terminal, and its third terminal coupled to the second power-supply terminal, or to a control signal input terminal that is normally at the same potential as the second power-supply terminal. A second active element has its first terminal coupled to the second power-supply terminal, its second terminal coupled through a resistor to the first power-supply terminal, and its third terminal coupled to the second terminal of the first active element. A reset signal is taken from the second terminal of the second active element. The control signal can be used to prevent current flow during static current measurements.
