Abstract :
Infinite network theory provides a computationally advantageous method for computing the threshold voltage of a narrow-channel or short-channel MOSFET. It takes into account the fringing of the electric field upward into the air and sideways into the oxide and semiconductor. This approach also has the advantages of smaller computer memory requirements and execution times as compared with the classical method.<>
