Abstract

PURPOSE:To set an arbitrary characteristics, by combining a plurality of characteristics. CONSTITUTION:The 1st differential amplifier consisting of transistors (TR)Q1, Q2, resistors R1, R2 and a constant current source I1, and the 2nd differential amplifier consisting of TRs Q3, Q4, resistors R3, R4, and a constant current source I2, are connected in parallel, by making load resistors RL1, RL2 in common. By setting values of the components in each differential amplifier to desired values, such as the resistors R1-R4 and the constant current sources I1, I2, a blind sector characteristics as shown in figure, for example, can be obtained for the output of addition of each differential amplifier.
