Title: Improvements in or relating to transistor amplifiers
IPC: H03F1/30
Filed: 1958-12-04
Abstract: 896,099. Transistor amplifier circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 4, 1958 [Dec. 7, 1957], No. 39130/58. Class 40(6). A multi-stage transistor amplifier adapted to operate from a rectified A.C. supply has the final stage operated in common collector configuration with the collector connected to a poorly smoothed supply and its base effectively connected for D.C. to the collector of a preceding stage deriving its supply from a relatively well smoothed supply. In the Figure, an output stage 4 feeding a loud-speaker 5 derives its supply from the input of the smoothing circuit 9, 11, 12. The base of the transistor is connected through a further common collector stage to a common emitter stage 2 having its collector connected to the output of the smoothing circuit. It is arranged that the D.C. voltage across the loud-speaker is about half of that applied to the transistor 4
