Abstract

PURPOSE:To improve the linearity of an input/output voltage in the vicinity of a clip voltage by providing a current detecting circuit for detecting the vicinity of the clip voltage, a differential amplifier for amplifying its detecting signal, and a latching circuit. CONSTITUTION:In case a supply voltage is lower than a base voltage of a clip use transistor 8, the transistor 8 is cut off, and a signal being higher by a base-emitter voltage (VBE6) of a transistor 6 than a signal voltage supplied to a base of the transistor 6 is obtained in an output terminal 9. In case of the vicinity of a clip voltage, both the transistors 6, 8 are turned on and a collector current flows to both the transistors. Subsequently, the collector current flowing to the transistor 8 is detected by a current detector 13, this detecting current is converted to a voltage, a clip detecting voltage is obtained, applied to a differential amplifier 14, and also, inputted to a latching circuit 15. Next, due to a positive feedback operation of the latching circuit 15, the transistor 8 is cut off quickly in the end, and a linear input/output characteristic is obtained.
