Abstract
PURPOSE: To obtain a linearizer which is easy to be adjusted and is not drifted by temperature by combining multiple non-linear elements which form a non-linear function of an operational amplifier, diodes and a constant voltage power source.
CONSTITUTION: An input signal Ei is converted into current I. When the voltage drop I.R due to a resistance R is smaller than voltage of a constant voltage power sourse e1, the outputs of operational amplifiers A1WA3 take positives and diodes D1WD3 become non-conductive. When the input voltage Ei increases and exceeds the voltages of the constant voltage source e1We3, the diodes D1WD3 become conductive one after another and current flows through resistors r1Wr3 connected with reverse input terminals 7, 10, 13 of the arithmetic amplifiers A1WA3 and output voltage EO is decreased.
