Abstract

An integrated circuit includes an active zone having a center portion adjoining a first side portion and a second side portion. A first transistor having a gate formed over one of the first channel regions in the center portion has a first threshold-voltage. A second transistor having a gate formed over one of the second channel regions in the center portion has a second threshold-voltage. A third transistor having a gate formed over one of the third channel regions in the first side portion has a third threshold-voltage. A fourth transistor having a gate formed over one of the fourth channel regions in the second side portion has a fourth threshold-voltage. A first average of the first threshold-voltage and the second threshold-voltage is larger than a second average of the third threshold-voltage and the fourth threshold-voltage by a predetermined threshold-voltage offset.
