Patent 7932771 was granted and assigned to Mitsumi Electric on April, 2011 by the United States Patent and Trademark Office.
A semiconductor device includes a semiconductor element including a current mirror circuit, a parasitic resistance formed at the current mirror circuit, and a connection terminal electrically connected to a part of the current mirror circuit via an electric conductor including a bonding wire, the connection terminal being configured to perform input and output relative to an outside of the semiconductor device; wherein a resistance value of the bonding wire is controlled so that a shift of an output electric current of the current mirror circuit based on the parasitic resistance is corrected.
