Abstract
PURPOSE:To cancel the fluctuation of an output due to the change of an input signal by making the input signal into a current mirror and composing a total feedback circuit. CONSTITUTION:To the collectors of transistors Q1, Q2 and Q3, the collectors of transistors Q4, Q5 and Q6 are connected respectively, and the transistors Q4 and Q5 and the transistor Q6 are current-mirror-connected. Between respective bases and collectors of the transistors Q4 and Q5, the emitter and base of transistors Q7 and Q8 are connected, and the collectors of the transistors Q7 and Q8 are grounded. To the common collector of the transistors Q3 and Q6, the base of a transistor Q9 is connected, the emitter of the transistor Q9 is connected to one edge of a constant current source 11 and the base of the transistor Q3 and applies a total feedback. To respective bases of the transistors Q1 and Q2, inputs 15 and 16 are connected, and an output terminal 17 is connected to the emitter of the transistor Q3.
