ABSTRACT:
An integrated circuit device having a simplified bias supply circuit for supplying bias power sources for a plurality of circuit units or cell units. The integrated circuit device cmprises: a cell unit array having a plurality of cell units disposed in a central portion of a semiconductor chip; a first power supply line and a second power supply line; and one or more common bias generating portions disposed at the periphery of the cell unit array, each of the common bias generating portions generating a single common bias voltage which differs from the potential of the second power supply line by a constant value. Each of the cell units comprises one or more logic circuit cells such as ECL type logic circuits, and an inner bias circuit which receives the common bias voltage and which generates a first inner bias voltage and a second inner bias voltage that are supplied to the respective logic circuit cell. The second inner bias voltage differs from the common bias voltage by a constant value, and the first inner bias voltage differs from the potential of the first power supply line at the cell unit by the value determined by the values of the elements in the inner bias circuit and by the common bias voltage.
