Abstract: Bias for the n cascade connected output transistors of a conventional series amplifier is obtained by applying successive increments, each 1/n times the output voltage available across the series connected conduction paths of these transistors to the control electrodes of the successive transistors in the cascade, except for the one connected to the load terminal. Drive signal is applied to the control electrode of this transistor. In accordance with the present invention, the drive signal is supplied via n cascade connected input transistors biased in similar fashion to the cascade connected output transistors, to develop across its conduction path a voltage approximately equal to 1/n times the amplifier output voltage. This way of applying drive signal to the series amplifier facilitates its connection with another series amplifier in push-pull amplifier configurations.

Abstract: Characteristics of photolithographically-defined planar semiconductor device pairs made from the same master are different, but many of the differences are regular in kind. To achieve a device pair in which the magnitude of the difference in the characteristics of the elements of the pair is reduced, two pairs are made from the same master. The first element of one pair is connected to the second element of the other pair so that the two operate as one composite element. The second element of the one pair is connected to the first element of the other, similarly for operation as another composite element the characteristics of which closely match those of the one composite element.
