Abstract

PURPOSE:To improve responsiveness by providing a capacitor between connection points in a circuit which extracts outputs from connection parts of cascaded transistors. CONSTITUTION:In a circuit which holds a high-rank power supply at a stable logical level and a low-rank power supply at a stable logical level, difference V1 in input logical level between input terminals 13 and 14 fixes forward voltages of transistors Q13 and Q14 to VF and voltage VF-V1 or VF+V1 appears at output terminal 15. This shows that the output voltage has no relation to the voltage of power supply 11. Since the responsiveness of this circuit depends chiefly upon resistances R11 and R12, capacitors C11 and C12 connected in parallel serve as speed- up capacitors, so that the responsiveness will be improved.
