Abstract

1308012 Two state trigger circuits ELEKTRO-APPARATE-WERKE-BERLIN-TREPTOW VEB 29 April 1970 20672/70 Heading H3T A temperature stable two state trigger circuit comprises two differential transistor amplifiers D1, D2 in cascade, an input terminal connected to one input of the first and positive and negative feedback being applied to the other input from respective outputs of the second amplifier, the negative feedback path including a further transistor 16 feeding a potentiometer 22, 23 supplying the feedback voltage. The positive feedback resistor 21 may be omitted and the negative feedback potentiometer as well as resistor 24 may be variable. The input may be derived from a photo-cell, Fig. 3, not shown.
