Applications of the Transit-Time Current — Voltage Relationships to Negative — Conductance Devices

Abstract

The current-voltage relationships developed in the previous paper is applied to two examples: the transistor transit-time oscillator and the Read avalanche diode. It is shown that transit time in the semiconductor alone is insufficient to create negative conductance which is essential for oscillation to take place. Instead additional phase shift must be introduced. In both examples treated in this paper, the additional phase shift comes from the carrier-injection mechanism.
