Abstract :
There has been an on going effort to improve RF performance in LDMOSFETs for high voltage applications. This paper examines the suitability of a 3D-RESURF LDMOSFET on SOI technology for RF power applications using the 3D-device simulator, Davinci. For the same blocking voltage rating, the 3D-RESURF device has improved current handling capability at high gate voltages. This in turn causes the transconductance to be higher, leading to overall better RF performance.
