| Abstract |
Early Field Effect Transistors incorporporated parasitic body diodes with poor characteristics. In many applications an external diode network was used to isolate diode resulting in a more complex hardware design. More recent FETs have faster integrated diodes, although these are still inferior to discrete components. This paper presents comparative loss measurements for an inverter with and without external diodes. It is shown that even with more recent FETs there is an advantage to using external isolation diodes. |
