PURPOSE:To simplify circuit constitution while improving the degree of integration by adjusting the ratio of reference currents to output currents of a current mirror circuit by utilizing an aluminum wiring resistor in an integrated circuit device containing the current mirror circuit. CONSTITUTION:With transistors Q1, Q2, N type regions 1, 4 are used as collectors, P type wells 2, 5 formed on the N type regions 1, 4 as bases and N type regions 3, 6 shaped on the P type wells 2, 5 as emitters. A slender resistor section 17 is formed between an emitter contact 12 for the transistor Q2 and an aluminum wiring section 16 and used as an emitter resistor R, and current difference by an Early effect is corrected. The shape of the resistor section 17 is not enlarged so much, and a special resistance element is not required. |
