Abstract

457,962. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. June 3, 1936, No. 15558. Convention date, Aug. 9, 1935. Addition to 457,928. [Class 40 (v)] An amplifier of electric oscillations arranged as described in the parent Specification is provided with a capacitative output impedance 5, 6, in order that the amplifier gain may be the same at all frequencies. The low negative plate voltage of the valve or valves 1, 2 is applied through resistances 3, 4 which are shunted by capacities 5, 6 of such valve that the inter-valve coupling or the output circuit presents a capacitative impedance. For very high frequencies, the capacities 5, 6 may be omitted, the inter-electrode capacities of the valves being sufficient for the purpose. The effective capacity may be further reduced by providing capacity reaction from the plate of a third valve to the grid of the first.
