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
