Abstract

PURPOSE:To avoid the effect of applied voltage, by flowing the bias current which is prescribed by an MISFET connected in series to an MISFET with the gain and the drain connected to each other and with the gate and the source connected to each other to the 2nd MISFET. CONSTITUTION:An enhancement type MISFETQB with the gate and the drain connected to each other is connected in series to a depression type MISFETQC with the gate and the source connected to each other. Then a certain bias current prescribed by the MISFETQC is supplied to the MISFETQB. As a result, a prescribed constant bias voltage which is not substantially affected by the applied voltage can be delivered between the drain and the source of the MISFETQB.
