Abstract

See full text

Standard cell circuits employing high aspect ratio voltage rails for reduced resistance are disclosed. In one aspect, a standard cell circuit is provided that employs a first high aspect ratio voltage rail configured to receive a first supply voltage. A second high aspect ratio voltage rail is employed that is disposed substantially parallel to the first high aspect ratio voltage rail. A voltage differential between the first and second high aspect ratio voltage rails is used to power a circuit device in the standard cell circuit. The first and second high aspect ratio voltage rails each have a height-to-width ratio greater than 1.0. The height of each respective first and second high aspect ratio voltage rail is greater than each respective width. Employing the first and second high aspect ratio voltage rails allows each to have a cross-sectional area that limits the resistance and corresponding IR drop.
