The Pierce diode with an external circuit: Simulations in the linear regime
William S. Lawson · Journal of Applied Physics · 1988
The linear theory for the eigenfrequencies of the extended Pierce diode for resistive, capacitive, and inductive external circuits is tested via computer simulation with the pdw1 code, and is verified to within the accuracy of the simulation (between 1% and 0.01% depending on the circumstances). The simulations were remarkably inexpensive in terms of computer time, and could have been performed on a personal computer.
