摘要： The positive input terminal (1), the negative input terminal (2) and the differential amplifier (10) are connected to the voltage converting circuit (9a). The differential amplifier (10) is composed of the operational amplifier (6) and the resistors (5a, 5b, 5c and 5d). The voltage converting circuit (9a) includes NPN transistors (91, 92 and 93). The base of the transistor (91) is connected to the positive input terminal (1) and the base of the transistor (92) is connected to the reference potential input end (3) to which the reference potential (V.sub.x) is applied, respectively. The collectors of the transistors (91 and 92) are connected to the potential point (81) in common and the emitters are connected to the other end of the resistor (5a). The base of the transistor (93) is connected to the negative input terminal (2), the collector is connected to the potential point (81) and the emitter is connected to the other end of the resistor (5c). It is prevented that the voltage applied to the differential amplifier (10) considerably differs from the desired value (V.phi.). The delay time of the output potential for a sharp change in the input voltage is shortened.
