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, the 2nd differential amplifier consisting of TRs Q3, Q4, resistors R3, R4 and a constant current source I2, and the 3rd differential amplifier consisting of TRs Q5, Q6, resistors R5, R6 and a constant current source I3, are connected in parallel with common load resistors RL1, RL2. The values of the resistors R1-R6 and the constant current sources I1-I3 of each differential amplifier are set to a prescribed value, allowing to obtain an output having a blind sector as shown in figure, for example, as the output of addition of each differential amplifier.
