PURPOSE: A circuit for improving a regeneration field of a cross feed type of a feedback system is provided to compose a simple circuit by selecting a mutual intersection negative feedback system and to prevent degradation of characteristics of signal to noise by composing a complex circuit. CONSTITUTION: A circuit for improving a regeneration field of a cross feed type of a feedback system includes adding and subtracting operation portions(15, 25), a left input step(50), a right input step(60), output steps(70, 80) and circle conveying functional portions(40, 30). The subtraction input terminal(-) of the adding and subtracting operation portions(15, 25) connecting the left input step(50) and the right input step(60) to the addition input terminal(+) is connected to the output steps(70, 80) of the adding and subtracting operation portions(15, 25) through the circle conveying functional portions(40, 30) with the feedback cross feed conveying functions(TF1, TF2). The left and right output signals of the adding and subtracting operation portions(15, 25) make the cross feedback to the subtraction input terminal(-) of the adding and subtracting operation portions(15, 25).
