Title: Simulation method for field effect transistor and device thereof
Inventor: HASHIMOTO MIYUKI
IPC: H01L27/08
Filed: 2001-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a simulation device of a field effect transistor capable of simulating the field effect transistor, even if the transistor characteristics are deteriorated. SOLUTION: To the drain of a field effect transistor Q1 of an n-channel, diode D1 and D2 connected in anti-parallel constituting a voltage drop means 1 are connected. In region where a voltage Vds between the drain and the source is low, the change in drain/source current Ids is small at a voltage Vgs between the gate and the source such as in a state where the transistor characteristics are deteriorated, and as the voltage Vgs between the gate and the source increases, the drain. source current Ids monotonously increases as well and will not become saturated.  When it exceeds the region where the voltage Vds between the drain and the source is low, the drain/source current Ids increases monotonously as well as the voltage Vds between the drain and the source increases and the drain/source current Ids starts to be saturated, when the voltage Vds between the drain and the source is increased further.
