| 摘要 |
The present differential amplifier comprises two amplifier stages, preferably transistor stages, coupled to each other through a two terminal coupling network having a non-linear and point- or radial-symmetrical characteristic whereby the non-linearity in the input voltage output current characteristic of the amplifier stages is compensated by a corresponding non-linearity of the two terminal coupling network so that the characteristic of the differential amplifier is linearized over a wide range.
