Abstract

1,187,564. Semi-conductor oscillators. NATIONAL RESEARCH DEVELOPMENT CORP. 21 March, 1967 [8 Feb., 1966], No. 59215/69. Divided out of 1,187,563. Heading H3T. [Also in Division H1] A Gunn effect oscillator comprises a third electrode on the material between the anode and cathode and a circuit between the third electrode and the cathode which produces Gunn effect oscillations at a frequency independent of the cathode-anode distance. In one arrangement (Fig. 4) the third electrode F is capacitively connected to the cathode K so that as a domain D reaches F, the resulting signal transmitted back to K results in the formation of another domain. In another arrangement a constant voltage supply is connected between F and K and a constantcurrent supply between F and anode A.
