STROMSPIEGELSCHALTUNG.

摘要

The circuit comprises two parallel branches, the first of which consists of a series chain of two diode-connected transistors (1,2) with base connected to collector, whilst the second branch has the base-emitter junction of two transistors (3,4) connected in series, their collectors being jointly connected to a second output terminal (7). The input (5) is connected to the joined base and emitter of the first diode-connected transistor and the base of the third transistor, whilst the output (6) is produced at the emitter of the second diode-connected transistor that is joined to the emitter of the fourth transistor. The input/output connections may be reversed in which case the output would be the inverse ratio of the square root of the current amplification factor of the transistors.
