Abstract : Relay circuits comprising a tunnel diode and a transistor operating as a switch are briefly described. The principal circuit has a rectangular 'input-output' characteristic, and its operation and release thresholds depend only slightly on the ambient temperature and supply voltage; the capacitor C increases the noise immunity but decreases the maximum switching frequency. The second circuit has five different input-output characteristics; the relay is much more sensitive but its thresholds depend on the supply voltage. The switching is determined by the transistor characteristics; a switching frequency of 500 kc was easily obtained in experimental tests. Characteristics of the tunnel diode, transistor, and combined characteristics of the relay are briefly discussed; principal formulas are supplied. (Author)
