Abstract

PURPOSE: To detect an absolute value through a simple circuit configuration by using a diode, an outputting transistor and a constant current load.
CONSTITUTION: An input voltage is impressed on an input terminal 21, which is connected to a noninverted input terminal of an operational amplifier 22. An output terminal of the operational amplifier 22 is connected to an inverted input terminal. Transistors 231, 241, 246 are of a shape, and a level shift diode 242 and a transistor 243 are of a shape in emitter area. An input voltage is subjected to a half-wave rectification; when a condenser is connected between an output terminal 25 and an earthing terminal, an output voltage is integrated to obtain an absolute value output.
