Title: Improvements in or relating to transistor amplifiers
Inventor: KITCHIN HARRY DONALD
IPC: H03F1/30
Filed: 1963-03-13
Abstract: 1,068,811. Transistor amplifying circuits. MARCONI CO. Ltd. Jan. 28, 1964 [March 13, 1963], No. 9879/63. Heading H3T. In a two-or-morestage transistor amplifier provided with stabilizing D.C. negative feedback from a later to an earlier stage and also provided with separate A.C. negative feedback derived from the load of the later stage, the D.C. negative feedback is derived from a resistor connected in series in the emitter-collector circuit of the later transistor, the A.C. feedback concomitant therewith being neutralized by A.C. positive feedback derived from a second resistor connected in the same series circuit as the first and combined with the feedback therefrom through a capacitor to eliminate the concomitant D.C. positive feedback. By this means in a circuit wherein the load of the later stage is reactive, the A.C. feedback from that stage may be made to depend solely upon the output voltage from that stage. In the circuit illustrated A.C. feedback from the load L of the second stage is applied to the emitter of transistor T1 through capcitor C3. Stabilizing feedback is applied through resistor R4 from R3; the A.C. feedback which accompanies it is balanced out by feedback fed from resistor R5 through resistor R6 and capacitor C3. For exact compensation the resistances of resistors. R4 and R6 should be in the same ratio as those of resistors R3 and R5.
