Semiconductor diodes bipolar junction transistors field-effect transistors transistor amplifiers frequency response operational amplifiers differential and multistage amplifiers integrated circuits.

Isolated gate bipolar transistors (IGBTs) are widely used power semiconductor devices. Properly designed drivers are extremely important for the effective use of IGBTs.

A new two dimensional numerical analysis program SDA-1 is presented for semiconductor devices. It is applicable to two dimensional finite element numerical analysis of bipolar transistors and MOSFET.
