Abstract

PURPOSE: To improve nonlinearity of the transistor, by connecting resistances to emitters of differential transistors, which have bases connected commonly, and the diode which biases these transistors.
CONSTITUTION: Resistances R1∼R4 are connected to emitters of differential transistors Q1 and Q2, which have bases connected commonly, and diode-connected transistors Q3 and Q4 which bias transistors Q1 and Q2. Pairing of transistors Q1∼ Q4 is improved by adjusting resistances R1∼R4 properly.
