Abstract
PURPOSE: To simplify the constitution by connecting differentially a plurality of transistors and a feed back transistor to one another and feeding back output of a plurality of the transistors through a diode to the feed back transistor.
CONSTITUTION: In the case of the signal impressed to input terminals 1 and 2 being zero, a substantially equal current flows through FFT5 and 6 and a diode 11, 12 become conductive and negative feed back to a gate of FFT18 is carried out through transistors 13 and 15. Thus, output level of the output terminal 17 becomes zero. Then, in the case of the input signal level of the input terminal 1 being larger than that of the input terminal 2, the negative feed back is carried out through a diode 11 and potential of the output terminal 17 becomes equal to the signal level of the input terminal 1. Similarly, in the case of the input signal level of the input terminal 2 being larger than that of the input terminal 1, the potential of the output terminal 17 becomes equal to the signal level of the input terminal 2.
