cascoden.

/ˈkaskəʊd/

Etymology: < casc- (in cascade n.) + -ode (in cathode n.).

(See quot. 1958.) Also attributive.Quot. 1939 does not illustrate the current sense: see quot. 1948¹.

1939 Hunt & 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.

1948 H. Wallman et al. in Proc. IRE 36 701/1 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.

1948 H. Wallman et al. in Proc. IRE 36 701/1 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.

1955 Electronic Engin. 27 323 The features of the cascode type of amplifier.

1958 Chambers'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.

1960 Electronic Engin. 32 44 A transistor cascode amplifier does not require neutralization.
