#GaN Technology: A Lean, Green (Power) Machine

To provide drop-in replacements for Si MOSFETs, GaN FET suppliers redesigned their products to operate in enhancement mode, typically by placing a low-voltage Si switch in series with the depletion-mode GaN to form a cascode configuration. A native enhancement-mode GaN device is possible, too, but driving it is more complicated because the GaN gate is resistive, voltage-sensitive, and requires a minimum current to remain on.
