A Novel Stacked Cell Layout for High-Frequency Power Applications

open access: yesIEEE Microwave and Wireless Components Letters, 2021
This letter presents an innovative stacked cell, where the common source device is split in to two smaller devices leading to a more compact and symmetric structure, with almost negligible parasitics associated with the transistor connection. This novel configuration is rigorously compared, for the first time, with the two classical approaches commonly
