Abstract
A voltage sensitive trigger circuit with a threshold which must be temperature and supply-voltage independent. To this end, a preamplifier is employed which in itself is not only provided with negative feedback but which also receives a current which is derived from that trigger transistor, which in the quiescent condition is conducting.
