Abstract
1,063,763. Current stabilizers. LE MATERIAL ELECTRIQUE S.W. Feb. 4, 1965 [Feb.7, 1964], No.4872/65. Heading G3X. The current from a source 3 is stabilized by a circuit including transistors T1, T2 and resistors R2, R4, R5, R6 interconnected as shown. The emitter of transistor T1 is connected to a reference voltage source 1 and the Specification shows that the collector of transistor T2 provides the required stabilized output.
