Abstract :
The state-of-the-art power switch is the insulated gate transistor (IGT) in which MOS and bipolar devices are functionally merged. It is shown that with the advent of BiCMOS technology, lateral IGT-like structures can easily be fabricated together with signal-conditioning and logic circuits on the same die, providing smart power. With few process modifications, a wide variety of power devices having different current and speed characteristics can be realized simply by varying cell designs and/or chip layouts. It is concluded that the lateral-MOS-controlled thyristor, having the lowest forward voltage drop among all lateral devices appears to be an attractive choice for future smart-power applications
