Input bias adjustment circuit for amplifier |
摘要 |
In feedback type amplifier including a differential transistor pair, the bias current to at least one of the differential transistors is provided by a source of current proportional to the DC currents through the differential pair, a first transistor connected in series with the current source and having its base coupled to the base of a second opposite conductivity type transistor so that both will conduct the same current, and a further transistor of the opposite conductivity type which is connected in series with the second transistor and provides its base current to one of the differential transistors.
