1939Hunt & Hickman in Rev. Scient. Instruments X. 16/2 This tube connection we have called the ‘cascode’... It is generally useful for d.c. amplifier work in which it is inconvenient to supply the additional bias voltages for a pentode. The dual triode, as connected, may be shown to be equivalent to a single triode. 1948H. Wallman et al. in Proc. Inst. Radio Engin. XXXVI. 701/1 Search for a concise name for the grounded-cathode, grounded-grid combination led to the designation ‘cascode’, after a somewhat similar arrangement employed by Hunt and Hickman. Ibid., The low-noise property that forms the feature of the present circuit is, however, entirely unconnected with the original use of the cascode as a d.c. amplifier in a voltage stabilizer. 1955Electronic Engin. XXVII. 323 The features of the cascode type of amplifier. 1958Chambers's Techn. Dict. 964/1 Cascode, thermionic valve circuit in which a grounded-cathode triode followed by a grounded-grid triode provides a low noise amplifier for very high radio frequencies. 1960Electronic Engin. XXXII. 44 A transistor cascode amplifier does not require neutralization. |
