摘要：

A current-discrimination arrangement, in particular for use in stabilizing circuits, comprises two cross-coupled transistors. The current to be discriminated is applied in parallel to both transistors. For small currents both transistors conduct to the same extent, while at a current I=2(KT/qR), in which R is the resistance value of the collector load impedances of the two transistors, the circuit becomes bistable. The steep characteristic at the transition from non-stable to the bistable operation is used as discrimination characteristic.
