Abstract
1,139,744. Transistor amplifying circuits. SIEMENS A.G. 17 June, 1966 [18 June, 1965], No. 27158/66. Heading H3T. In a differential amplifier a pair of complementary transistors are connected in series with their bases in separate input circuits, their emitters being connected together by a network including a capacitor CE in series with a resistor RE 2 of relatively low value, both being in parallel with a relatively high value resistor RE 1 which determines the working points of the transistors, in conjunction with a voltage source UB connected to the base of one of the transistors. The arrangement substantially eliminates amplification of any co-phasal input signals U 1 , U 2 .
