Analysis and Design of High Efficiency, High Conversion Ratio, DC-DC Power Converters

eGaN® FETs in High Frequency Resonant Converters

Distributed power systems are prevalent in telecommunications, networking, and high-end server applications and generally utilize a 48 V bus voltage adopted from the telecom industry. From the 48 V bus, a number of isolated point of load (POL) converters power the end loads, with isolation being required for safety. The traditional distributed power architecture (DPA), shown in figure 1(a), use...

High-frequency graphene voltage amplifier.

While graphene transistors have proven capable of delivering gigahertz-range cutoff frequencies, applying the devices to RF circuits has been largely hindered by the lack of current saturation in the zero band gap graphene. Herein, the first high-frequency voltage amplifier is demonstrated using large-area chemical vapor deposition grown graphene. The graphene field-effect transistor (GFET) has...
