Current-voltage characteristics and noise performance of a static induction transistor for video frequency

The current-voltage characteristics and the noise properties of the triode-like-mode static induction transistor (SIT) have been examined to estimate the noise performance of the SIT for preamplifier circuits in video frequency regions. Empirical formulas for the current-voltage characteristics and the input equivalent noise resistance have been obtained. A figure of merit for the noise performance of the SIT amplifier is introduced. It is used to determine the operating point at which the noise level becomes minimum.<
