摘要
A differential amplifier manufactured in integrated circuit form in a semiconductor substrate includes first and second differentially coupled input transistors. The emitters of the input transistors are coupled to a first source of supply voltage (e.g. V.sub. cc) and the collectors of the input transistors are coupled via load devices to a second source of supply voltage (e.g. ground). An RC gain reduction network is provided between the collectors of the input transistors and implemented in such a manner so as to provide substantially equal parasitic capacitances at the collectors of each of the input devices.
