Abstract

1,034,637. Transistor amplifying circuits. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. March 16, 1965 [March 19, 1964], No. 11166/65. Heading H3T. [Also in Division G4] A direct voltage differential amplifier comprises two 4-pole direct voltage amplifiers V1, V<SP>1</SP>, each with an output terminal earthed, two feedback resistances R 0 , R<SP>1</SP> 0 connected between the remaining output terminal 4, 4<SP>1</SP> of an amplifier and an input terminal 1, 1<SP>1</SP> thereof; input voltages U E1 , U E2 connected to the remaining input terminals 2, 2<SP>1</SP> of the amplifiers with further resistances R 1 , R<SP>1</SP> 1 respectively connected between the live output terminal 4<SP>1</SP> of amplifier V<SP>1</SP> and the feedback input terminal 1 of amplifier V, and between the feedback input terminal 1<SP>1</SP> of amplifier V' and earth; the output U A between output terminal 4<SP>1</SP> and earth being equal to U E1 -U E2 for R 0 R 0 <SP>1</SP> = R 1 R 1 <SP>1</SP>. The amplifiers may be transistorized.
