ABSTRACT:
A multistage transistor amplifier for amplifying alternating voltages which comprises at least two successive cascade-connected amplifier stages having d.c. feedback. A following amplifier stage is a.c. coupled to the output of the cascade-connected amplifier stages and a resistor is connected between the output of the cascade-connected amplifier stages and the input of the following amplifier stage. The cascade-connected amplifier stages supply the following amplifier stage with direct current, the d.c. operating resistance for the following amplifier stage including the cascade-connected amplifier stages and the resistor.
