Small signal and noise characteristics for GaAs field-effect transistors are derived with the saturated drift velocity of the carriers underneath the gate taken into account. The noise contributed by the saturated carriers is nonnegligible and in mos

It is shown that source and drain charges are not state variables in an FET, especially for source-drain voltages near zero. This behavior, observed in the model proposed in [2], is a genuine manifestation of the physics of FET's and is not a sign of

We have developed a GaAs FET model suitable for SPICE Circuit simulations. The dc equations are accurate to about 1 percent of the maximum drain current. A simple but accurate interpolation formula for drain current as a function of gate-to-source vo

The noise and signal properties of Read-type avalanche diodes under large-signal levels are examined. In contrast to most other previous theories, we include the saturation current in the equations rigorously from the beginning. We find that the nois

In this paper we show that very large displacement currents may flow in high power Read diodes, especially when they are operated in the pulsed mode. These displacement currents may have peak amplitudes which are larger than the maximum possible cond

We have tested many GaAs IMPATT diodes under high power pulsed conditions and found that the best power output and efficiency occur at higher frequencies in the pulsed mode than in the CW mode. This phenomenon can be understood by considering the eff

Es wird die Elektronenstruktur gewisser binärer ferromagnetischer Legierungen untersucht und mit der Größe ihrer Sättigungsmagnetisierung in Verbindung gebracht. Im innenzentriert kubischen Gitter spalten die 3 d-Atomzustände in zwei energetisch

Beim eindimensionalen Gitter wird systematisch zwischen zwei Arten von Oberflächenzuständen (O.Z.) unterschieden, je nachdem sie aus einem oder aus zwei Bändern entstammen. Die O.Z. erster Art werden aus einem neuen, einfachen Gesichtspunkt heraus

An attempt is made to determine some of the factors responsible for the noise performance of avalanche diodes. In particular we are interested whether there are any lower lids in the noise measure. We derive a theorem which shows that there is a lowe
