Abstract
PURPOSE: To make a faithful signal transmission possible by inserting bias adjusting transistors, which share load resistances with output transistors, in parallel to output transistors and performing the adjustment of bias voltages by these inserted transistors.
CONSTITUTION: Bias adjusting transistors Q5, Q6 and Q7 are connected in parallel to red, green and blue output transistors Q1, Q2 and Q3 so that load resistances R1, R2 and R3 may be shared load resistances. Then, even if bias adjustment is performed by variable resistances VR1, VR2 and VR3, collector currents of transistors Q1, Q2 and Q3 are always fixed, and the gain band width product in transistors Q1, Q2 and Q3 can be always set to the same value, thus making a faithful signal transmission possible.
