Abstract

1,017,550. Amplifier circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 13, 1964 [Nov. 27, 1963], No. 46877/63. Headings H3T and H3W. In an amplifier having a grounded grid or common base input stage T1, negative feedback (via R2) and positive feedback (via R3) are provided so as to reduce the input resistance at I to zero or a negative value. The gain is adjustable by variation of R2. Complementary transistors may be used.
