Abstract :
A circuit model of conventional vacuum field emission triode amplifier is developed in this article. The parameters of components in this model are calculated or estimated. Depending on Y parameters, the power gain and the cut off frequency of this device are calculated. The result shows that the cut off frequency is proportional to the gain of device gm and inversely proportional to grid-cathode capacitance Cgc and grid-anode capacitance Cga. Comparing to the experiment result, the result in this article is in accord with the experiment
