摘要： A first partial circuit is formed by grounding the emitter electrode of a first negative differential resistive element, connecting the emitter electrode of a second negative differential resistive element to the collector electrode of the first negative differential resistive element, and connecting a first field-effect transistor in parallel with the first negative differential resistive element. A second partial circuit is formed by grounding the emitter electrode of a third negative differential resistive element, connecting the emitter electrode of a fourth negative differential resistive element to the collector electrode of the third negative differential resistive element, and connecting a second field-effect transistor in parallel with the third negative differential resistive element. An output from the first partial circuit is input to the input of the second partial circuit. The inversion of the output of the second partial circuit is input to the input of the first partial circuit. A clock signal and a signal whose phase is opposite to that of the clock signal are applied to the collector electrodes of the second and fourth negative differential resistive elements, respectively. A frequency-divided signal of the clock signal is output from each partial circuit.

摘要： A self-seeking current controlled electronic switching network comprised of a plurality of cascaded stages of switching matrices. Each vertical multiple has an associate RC network for controlling the duration of the turned-on time period of the crosspoints during a route search. The RC circuit controlled time periods are selected to make each stage of the network run at an independent frequency, the frequencies being selected as a function of (a) the dynamic biasing changes which occur in the crosspoints responsive to the turning on and off, (b) the dynamic tapering which occurs in the network responsive to busy vertical conditions, and (c) the frequency of preceding stages.
