Abstract :
A state-of-the-art 0.5-μm-rule thin-film SOI power MOSFET was fabricated to evaluate its radio-frequency (RF) performance. The impact of the device structural parameters, such as channel length and drain offset length, on the RF performance of thin-film SOI power MOSFETs was also investigated. The fabricated device with channel length of 0.5 μm and drain offset length of 0.4 μm showed excellent performance. Its breakdown voltage was more than 10 V, which is sufficient for a lithium ion battery to be used as a power source. Its cutoff and maximum oscillation frequencies were 14.7 and 19 GHz, respectively. Its power-added efficiency at 2 GHz was 64%
