Abstract

PURPOSE:To minimize the current flowing through the switching element and prevent the generation of distortion without deteriorating S/N by separating input current and output current flowing through FET in circuit. CONSTITUTION:The return resistance Ro is provided between the inverting input and output. FET 2 ON and OFF controlled by a predetermined signal is provided between the inverting input of the operational amplifier A1 earthed non-inverting input and a predetermined input signal Vi. The current i1 corresponding to the input signal vi is impressed to the input, and the output current io is supplied to FET 2 by using the current converting means 10 guiding out the output current of k.i1 (k is a constant smaller than 1). Accordingly, the output current passing through FET 2 and the input current if can be separated in circuit.
