Title: Improvements in or relating to electric semi-conductor amplifiers
IPC: H01L29/00
Filed: 1952-03-07
Abstract: 728,449. Semi-conductor amplifiers. GENERAL ELECTRIC CO., Ltd., and PLUMMER, A. R. F. Feb. 19, 1953 [March 7, 1952], No. 6007/52. Class 37. A transistor amplifier comprises an elongated body 1 of semi-conductor material such as germanium, of one conductivity type, with an emitter electrode 4 near one end and a collector electrode 5 near the other, and means between these electrodes for amplifying the number of charge carriers injected at the emitter and flowing towards the collector. Ohmic electrodes 2 and 3 at the ends of the body provide an electric field to urge minority current carriers towards the collector end. The means to increase the number of carriers comprises a plurality of pairs of electrodes, each pair comprising an emitter 6 and collector 7, connected to a biasing battery 11. In each case, the holes flowing towards the collector will result in equal or greater current flowing through the contact and therefor through the associated emitter contact, so that the number of injected carriers in the body is increased by each pair of collector-emitter electrodes. Signals applied to the input terminals 12 associated with the first emitter electrode therefore result in amplified signals appearing in output terminals 13 associated with the final collector electrode. The lifetime of the minority carriers should be long and the electrodes should therefore be as close together as possible. A high voltage amplification can be obtained. Reference has been directed by the Comptroller to Specification 700,236.
