For example, dummy NMOS transistors MND1 (MND1a and MND1b) and MND2 (MND2a and MND2b) are connected to drain outputs of NMOS transistors MN1 and MN2 operated according to differential input signals Din_p and Din_n, respectively. The MND1 is arranged adjacent to the MN1, and a source of the MND1a and a drain of the MN1 share a diffusion layer. The MND2 is arranged adjacent to the MN2, and a source of the MND2a and a drain of the MN2 share a diffusion layer. The MND1 and the MND2 function as dummy transistors for suppressing variations in process of the MN1 and the MN2 and, and besides, they also function as means for adjusting the offset voltage by appropriately applying an offset-amount setting signal OFST to each gate to provide a capacitor to either the MN1 or the MN2.Type: GrantFiled: October 4, 2010Date of Patent: July 8, 2014Assignee: Hitachi, Ltd.Inventors: Koji Fukuda, Hiroki Yamashita
