Abstract

1,274,660. Transistor amplifying circuits. SOIL MECHANICS (EQUIPMENT) Ltd. 5 Jan., 1970 [8 Nov., 1968], No. 53108/68. Heading H3T. [Also in Divisions G1 and G4] An amplifying arrangement comprises transistors TR1, TR2, TR3, the transistors TR1, TR2 being connected as a feed back amplifier and TR3 acting as an emitter follower to provide a low impedance output. The arrangement has an extended low frequency response, is linear over its range and is insensitive to supply voltage variations.
